Archlinux and systemd (re)packaging impacts systemd_notify detection on arch

[Gary Buhrmaster <gary.buhrmaster@…>]

A report on the irc dev channel by JohnBergqvist on 2016-03-27 mentioned that archlinux has repackaged systemd in such a way that the pkg-config check in MythTV configure does not detected the availability of systemd libraries. This is likely the same as reported at ​https://bbs.archlinux.org/viewtopic.php?id=209316 where arch has merged various systemd components into the one package.

This ticket is just so the issue will not be forgotten.

I will add creating a patch (and the installing of an arch system to test the patch) to my growing TODO list, but if someone gets their first, excellent.

Weakly tested (it compiles!) trivial patch....
