Subject: [PATCH] libsystemd: drop unexported sd-utf8

It had two symbols which were not actually exported because they were not
listed in libsystemd.sym. They were also entirely unused in our codebase.
I don't think it makes much sense to export just those two functions, and
it doesn't make to build a string processing library in systemd either.

History of the file shows that it was created in
faaa5728d956b7f0d24f27f3341d0b9fff30af00 'utf8: export utf8 validation functions as part of sd-bus'
and hasn't gone even one non-trivial change since then ;)
