builtin-am: implement -u/--utf8

Since d1c5f2a (Add git-am, applymbox replacement., 2005-10-07),
git-am.sh supported the -u,--utf8 option. If set, the -u option will be
passed to git-mailinfo to re-code the commit log message and authorship
in the charset specified by i18n.commitencoding. If unset, the -n option
will be passed to git-mailinfo, which disables the re-encoding.

Since d84029b (--utf8 is now default for 'git-am', 2007-01-08), --utf8
is specified by default in git-am.sh.

Re-implement the above in builtin/am.c.
