cmd/go/internal/work: more TestRespectSetgidDir fixes

Browse Source 
Hopefully the last refactoring of TestRespectGroupSticky:
* Properly tested (+simplified) FreeBSD fix
* Tested on Darwin (10.12.4)
* Rename to TestRespectSetgidDir (I believe this is the accepted
  terminology)

Fixes golang/go#19596.
