[sapling] run .t tests for getdeps sapling cli build

Summary:
Connect up the sapling *.t tests so that github CI has visible cli test status.

To get them to run:
 * some needed fbpython on path. I included a shim for that in the test makefile target.
 * test-rust-hooks: Command not found message,  added a glob
 * test-identity.t: add a glob for the sapling version
 * test-eolfilename.t: output order was unstable, added sorts to make stable
 * helpers-testrepo.sh: fix assumption that system hg would be able to read test repo, check if its Sapling first.
 * added a manifest for the hexdump utility some of the tests required
 * excluded a few remaining tests (see comments in Makefile for reason)
 * fixed getdeps support for generating actions steps for test only dependencies

NB  the tests run as "hg".  The expectations would need to be updated if we were to run as "sl"

Test Plan:

enter ubuntu 22.04 toolbox:
`toolbox enter ubuntu-toolbox-22.04 `

make sure system packages are installed
`./build/fbcode_builder/getdeps.py install-system-deps --recursive  sapling`

build sapling (and any depedencieds it requires)
`./build/fbcode_builder/getdeps.py build --allow-system-packages --src-dir=. sapling`

run the tests.  64 concurrent jobs worked well on my 64GB machine and took 2m10s.
```
./build/fbcode_builder/getdeps.py test --allow-system-packages --src-dir=. sapling --num-jobs=64

+# Thrift enabled getdeps CLI build for use with Mononoke or EdenFS
+
+Mononoke and EdenFS need the thrift enabled sapling CLI built via getdeps. Check github actions to see current OS version the Sapling CLI Getdeps CI runs with.
+
+This build also provides a way to run the sapling .t tests in github CI and locally.
+
+When building locally you don't need to separately build all the dependencies like the github CI does, command line steps are:
+
+make sure required system packages are installed:
+`./build/fbcode_builder/getdeps.py install-system-deps --recursive sapling`
+
+build sapling (and any dependencies it requires):
+`./build/fbcode_builder/getdeps.py build --allow-system-packages --src-dir=. sapling`
+
+you can find the built binaries via:
+`./build/fbcode_builder/getdeps.py show-inst-dir --allow-system-packages --src-dir=. sapling`
+
+run the tests (you can use --num-jobs=N to adjust concurrency):
+`./build/fbcode_builder/getdeps.py test --allow-system-packages --src-dir=. --num-jobs=64 sapling`
+
+to iterate on one test run with --retry 0 --filter:
+`./build/fbcode_builder/getdeps.py test --allow-system-packages --src-dir=. sapling --retry 0 --filter test-check-execute.t`
+
+to run multiple tests with --filter separate with spaces:
+`./build/fbcode_builder/getdeps.py test --allow-system-packages --src-dir=. sapling --retry 0 --filter "test-include-fail.t test-matcher-lots-of-globs.t"`
+
+The getdeps build doesn't currently build/test ISL or other node integration.
