[PATCH v3] git-send-email: use ! to indicate relative path to command

[Gregory Anders <greg@gpanders.com>]

When the smtpServer config option is prefixed with a ! character, the
value of the option should be interpreted as a command to look up on
PATH.

Remove the PATH lookup, since Perl's exec() does this already.

Thanks to Jeff King for the assist.
