[OE-core] [PATCH 7/7] multilib_global.bbclass: Fix non-multilib package provides [v2]

[Mark Hatle]

In non-multilib packages, configured in a multilib configuration we
need to adjust the system provides and rprovides to include the
virtual multilib variant.

This resolves a problem introduced in the
329d864f9bbf94ad3aae8df43d63fe10e4237e4f commit.  Where "allarch"
packages were suddenly providing all variants of an object.
