Clarify license on script files

As noted, Ivan has agreed to allow these scripts to be relicensed under
CC0.  We have one file under LGPL (a unit file we lifted wholesake from
systemd) and the ADTPro wrapper which I'm pretty sure Ivan wrote, but if
he didn't we need to fix its license to be the same as ADTPro.

Either way, to the best of my knowledge, this resolves the question of
how things are licensed explicitly.  (Closes #21)
