[OE-core] [PATCH 2/2] multilib: skip packages that provide virtual/kernel

[Bruce Ashfield]

Rather than keying on recipes that inherit kernel.bbclass, we should
be checking for providers of virtual/kernel when skipping kernel
recipes in multlib builds.

Not all providers of virtual/kernel inherit kernel.bbclass (notably
linux-dummy), so checking on the provider is a more complete check.

We need to be sure to check for inheritance of module-base as well, this
allows for packages that provides modules to avoid the multilib renaming.
