transplant: added 'HGREVISION' variable to the environment passed to the 'filter' command

Sometimes it is necessary to know the original revision ID in order to
correctly rewrite the patch or commit message when transplanting.  This
patch follows the pattern set by the existing 'HGUSER' environment variable,
and adds a test that covers both HGUSER and HGREVISION.
