graphics/MesaLib: make this build & install on NetBSD/powerpc.

 * Add hacks.mk to make -latomic visible for 64-bit atomics.
 * Turn off nouveau build, as we do not have the DRI libs for that.
 * Introduce PLIST.xa, turned off on powerpc, apparently this requires
   one of nouveau, freedreno, i815 or svga gallium drivers.
