base.bbclass: Fix incorrect setting of multilib PREFERRED_PROVIDER_virtual_pkg

PREFERRED_PROVIDER_virtual_pkg has been incorrectly set with more
than one multilib prefixes.  For example, if we have two alternative
multilibs lib64 and lib32, PREFERRED_PROVIDER_virtual_pkg will be
set to lib32-lib64-pkg or lib64-lib32-pkg, depending on which
multilib shows up first in the list.
