git-am: show the final log message on "Applying:" indicator

The "Applying:" message "git am" shows to tell the user which patch
is being applied has traditionally been to help identifying the
input, but we started showing the edited result since f23272f
(git-am -i: report rewritten title, 2007-12-04), because it was
found more confusing to show the original during an interactive
session.

Treat the modification by the applypatch-msg hook in a similar way
and use the edited result in the progress indication, even though
this is usually not interactive.
