Summary:
Port of D6798134 to fbsource. It eliminates module-import failures as well as errors like this:
```
mercurial.error.ForeignImportError: hgext.extlib.treedirstate: /home/phillco/.local/lib/python2.7/site-packages/hgext/extlib/treedirstate.so lives outside /..../hg
```
....that block other tests, like test-help.t
(Note: this ignores all push blocking failures!)
