[PATCH 1/3] builtin/am: obey --signoff also when --rebasing

[Giuseppe Bilotta <giuseppe.bilotta@gmail.com>]

Signoff is handled in parse_mail(), but not in parse_mail_rebasing(),
since the latter is only used when git-rebase calls git-am with the
--rebasing option, and --signoff is never passed in this case.

In order to introduce (in the upcoming commits) support for `git-rebase
--signoff`, we must make gi-am obey it also in the rebase case. This is
trivially fixed by moving the conditional addition of the signoff from
parse_mail() to the caller am_run(), after either of the parse_mail*()
functions were called.
