Subject: [PATCH] go/vcs: drop support for Google Code Project Hosting

The hosting service was shut down on January 25, 2016 and a few tests
started to fail like the following:

=== RUN   TestRepoRootForImportPath
--- FAIL: TestRepoRootForImportPath (2.47s)
	vcs_test.go:129: RepoRootForImport("code.google.com/p/go"):
unable to detect version control system for code.google.com/ path
FAIL

This change drops support for code.google.com and fixes test. See
http://google-opensource.blogspot.jp/2015/03/farewell-to-google-code.html
for further information.

Fixes golang/go#14105
