[OE-core] [PATCH] multilib: Tweak value of PN used for OVERRIDES

[Richard Purdie]

Currently, PN is used in overrides which is expanded to have a MLPREFIX. This
means and pn- overrides without the prefix would be ignored which is not what
is usually expected.

We noticed huge problems using poky-lsb with multilib since the per recipe
overrides were not applied. This adds in handling for PN with and without
the prefix. This should unbreak world-lsb builds on the autobuilder.
