Subject: [PATCH] libwebp: set meta.pkgConfigModules

Using the package from the pkgs fixpoint instead of
finalAttrs.finalPackage to mirror the other tests which
also (indirectly) use pkgs.libwebp. Slight disadvantage of this is that
it's not possible to test overridden variants of libwebp this way.
