multilib_global: Add handling of SIGGEN variables for multilib

multilib task signatures turned out to have issues since
SIGGEN_EXCLUDERECIPES_ABISAFE and SIGGEN_EXCLUDE_SAFE_RECIPE_DEP
did not have multilib mappings. This adds those mappings in which
in turn improves multilib task checksums to match the standard
non-mulitlib versions.
