Jun Wu 3d461ae600 check-ext: make checks stricter
Summary:
Enhance check-ext script to be more strict:

 - Only one foreign extension is allowed: `remotenames`
 - Require explicit path for in-repo extensions to avoid wrong extensions
   being tested

This would make the test more predicatable since system extensions
will be less likely to be imported. Explicit path is better than
setting `PYTHONPATH` since `hgext/name.py` could override
`hgext3rd/name.py` regardless of `PYTHONPATH`.

Test Plan: arc unit
