[src/trunk]: src/usr.bin/make make: reduce indentation in Var_Parse

description:
make: reduce indentation in Var_Parse

The extra condition had been necessary before FStr made memory
management simpler.

The Coverity annotation got out-of-date when the parameter was converted
to FStr since that type is not allocated on the heap, only its inner
members are.

No functional change.
