Add some additional patterns to the "filter Mercurial --debug output" list

Summary:
Modern Mercurial may emit some more patterns under "--debug".

This whole list is gross and can likely now be eliminated by increasing the minimum required Mercurial version (as arc has), but just paper over it for now.

Test Plan:
Locally, saw some views return to functional behavior that weren't previously working on a modern version of Mercurial.

The reproduction case is likely something in the vein of "repository is not writable by webserver, look at history view".
