base.bbclass: Expand PNBLACKLIST across multilibs too
The PNBLACKLIST feature does not currently work with multilibs,
because they have different ${PN}. The obvious thing to do is to
do this at the same point that we do the PREFERRED_PROVIDER
and PREFERRED_VERSION fixups. (Making the PNBLACKLIST check
do the for-each-multilib check requires it to do the multilib
list generation repeatedly.)
