Enable test cases and update dependencies (pingcap#57)

* mydump/reader: ensure we can't seek beyond EOF

* *: enable `make test` and ensure all test cases can be compiled

* vendor: update vendor

In glide we removed the -s and -u flags since they are on by default, and
removed --skip-test so that github.com/pingcap/check can be vendored.

* makefile: define every test as integration test until TOOL-308 is fixed
