phabricator: respect metadata sent by arc

Browse Source 
Previously we only respect hg:meta sent by phabsend. This patch makes it
respect local:commits sent by arc as well. This avoids issues where phabread
could lose the author information.

Test Plan:
Commit using a customized user, send the patch using arc to a test
Phabricator instance, and then read the patch using phabread. Make sure it
preserves the user information.
