multilib_global: Handle PREFERRED_RPROVIDER

cdcebd81c872cb7386c658998e27cf24e1d0447c results in:
NOTE: Resolving any missing task queue dependencies
NOTE: Multiple providers are available for runtime lib32-initd-functions (lib32-initscripts, lib32-lsbinitscripts)
Consider defining a PREFERRED_RPROVIDER entry to match lib32-initd-functions
and will occasionally pick a different value on the second stamps run
causing a test failure. Update the multilib code to handle
PREFERRED_RPROVIDER too.
There is a bigger worry here which is why the builds aren't deterministic. This is
caused by a bug in bitbake's providers.py and a separate fix will be sent for that
which would cause this test to always pass or always fail.
