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.

fnmatch(): Add test for r254091 (pattern with single backslash).

This test cannot be converted to an sh(1) test because the syntax would be
invalid.

Generate some tests for sh's case command from the fnmatch tests.

I'm committing the generated files because I don't like a build dependency
for the sh(1) tests, and they are small and will not change much.
