Make ext.py compatible with hg5 api

[JornVernee]

The HG api changes in version 5 to drop the first 2 parameters to mercurial.match.exact, which breaks the extension script.

This PR detects whether we're running on hg 5, and if so, calls the function without the first 2 arguments instead.

@edvbld There was one other call to mercurial.match.exact which I forgot to change earlier (but was caught by another test)... changed that as well.

Still good to go?

[edvbld]
