"Steal" single value variables in rbc inheritance
This behavior of "stealing" values from parent makefiles is needed to
match make. We already had similar behavior for list variables via
the __move_items function, but were missing it for single value
variables.
Test: ./out/rbcrun -mode rbc ./build/make/tests/run.rbc
