ci: Remove obsolete compiler-wrapper

We don't actually need this anymore. We were previously using it to find
ccache, but Meson will do this for us. Now that we pass
-Wl,--fatal-warnings, we don't need to pass -Werror to the link stage
either.

This removes two shell execs, one subshell, and one call to each of grep
and printf, per compile.
