config: fix make.defaults inherit of make.globals

Since commit e544ee13527a0568de2b556510280ed96fc1b3ff, make.defaults
inheritance of variables from make.globals has been broke, since that
commit excluded make.globals from expand_map. This broke settings like
PORTAGE_ELOG_CLASSES="${PORTAGE_ELOG_CLASSES} qa" from the developer
profile, as reported in bug #391323, comment #4.
