build: work around ccache/autotools warning-spamming bug
When using clang and ccache, builds spew lots of:
Clang: warning: argument unused during compilation
Upstream bug: https://bugzilla.samba.org/show_bug.cgi?id=8118
This is harmless, bug annoying. If ccache is being used and the
-Qunused-arguments flag is supported (clang), use it.
