LU-11329 misc: reorder Git .mailmap file

If there are multiple remappings of the same person (e.g. CFS to
Sun to Oracle to Whamcloud to Intel to Whamcloud2), the entries
in the .mailmap file need to be in chronological order, so that
older entries are mapped to the next email, which is mapped to
the next one, etc.  Otherwise, only a single remapping is done.

Add additional mapping for Patrick Farrell.
