build: remove -Qunused-arguments workaround for clang + ccache

Browse source 
This was added in 386efb7695 to
address spammy Clang warnings when building with ccache.

The issue was addressed in ccache 3.2
(https://bugzilla.samba.org/show_bug.cgi?id=8118, Nov 2014),
and from a look at all major distros, it's only Debian Jessie
that has a version of ccache older than that (3.1).

Therefore I think it's acceptable to drop this workaround, and
re-enable warnings for unused driver arguments (when compiling
using Clang).
