Gce tests (#33507)

* Fix 'Observed wheel commit () is not expected' issue (#32156) that has been creeping through many of ci/cd builds in our pipeline.

The existing code uses pipe to read from a rather large file (>50MB). Pipe however has buffer limit which by default in term of kb (https://man7.org/linux/man-pages/man7/pipe.7.html) so what we look for might not exist. We can fix this by tell unzip the exact file we are looking for. That file is pretty small so we should not hit buffer limit.

You might notice other surpises might still happen with this fix (e.g. many files that match ^__commit__). This sanity check goes back to 2 years ago by our veteran Kai (234b015) to sanity check issues with stale artifacts from previous builds or race conditions between builds. Further investigation on how builkite agent multi-tenant is setup might or might not simplify this logic further.
