arm64: vdso: Cleanup Makefiles
The recent changes to the vdso library for arm64 and the introduction of the compat vdso library have generated some misalignment in the Makefiles. Cleanup the Makefiles for vdso and vdso32 libraries: * Removing unused rules. * Unifying the displayed compilation messages. * Simplifying the generic library inclusion path for arm64 vdso.
