DIFF for mta.sh startupscript on freebsd-port 4.52.2

[Lars Kristiansen]

Thanks to JP for the Freebsd-port.

Have just been using it to upgrade to 4.52.
But mta.sh would not start.
Needed to edit line 72 in /usr/local/etc/rc.d/mta.sh

Here is diff:

        \( \( $_mta_osversion -ge 700000 \) -a \
                \( $_mta_osversion -lt 700007 \) \) ]
 then

+       _mta_rc_script="${_mta_rc_script}.sh"
