It's been there since the test was introduced and I'm not really sure
what was the original intention behind it, but it makes systemd sad:
[ 4.909056] systemd[1]: /usr/lib/systemd/tests/testdata/units/testsuite-44.service:13: Unknown key name 'LogTarget' in section 'Service', ignoring.
Those are all consumed by our parser, so they all support comments.
I was considering whether they should have a license header at all,
but in the end I decided to add it because those files are often created
by copying parts of real unit files. And if the real ones have a license,
then those might as well. It's easier to add it than to make an exception.
