multilib.bbclass: allow TARGET_VENDOR_virtclass-multilib to be overriden

If we set this bit, we can override the ugly "pokymllib32" to back to
"poky" (powerpc-pokymllib32-linux-gcc -> powerpc-poky-linux-gcc). I've
left this unset by default, but can be set by adding the following:

TARGET_VENDOR_virtclass-multilib-lib32 = "-poky"
