Integrate tools/regression/lib/libc/gen into the FreeBSD test suite

as lib/libc/tests/gen

The code in test-fnmatch that was used for generating:

- bin/sh/tests/builtins/case2.0
- bin/sh/tests/builtins/case3.0

has been left undisturbed. The target `make sh-tests` has been moved over
from tools/regression/lib/libc/gen/Makefile to
lib/libc/tests/gen/Makefile and made into a PHONY target

case2.0 and case3.0 test input generation isn't being done automatically.
This needs additional discussion.
