This patch converts the existing glob selftest (lib/globtest.c) to use
the KUnit framework (lib/glob_kunit.c).

The new test:

- Migrates all 64 test cases from the original test to the KUnit suite.
- Removes the custom 'verbose' module parameter as KUnit handles logging.
- Updates Kconfig.debug and Makefile to support the new KUnit test.
- Updates Kconfig and Makefile to remove the original selftest.
- Updates GLOB_SELFTEST to GLOB_KUNIT_TEST for arch/m68k/configs.

This commit is verified by `./tools/testing/kunit/kunit.py run`
with the .kunit/.kunitconfig:

```
CONFIG_KUNIT=y
CONFIG_GLOB_KUNIT_TEST=y
```

Thanks for your patch!

This is not the correct location for CONFIG_GLOB_KUNIT_TEST.
Please run "make savedefconfig" and inspect the resulting defconfig
file.

However, given GLOB_KUNIT_TEST defaults to KUNIT_ALL_TESTS, which
is set to "m" in the m68k defconfigs, there is no need to add
"CONFIG_GLOB_KUNIT_TEST=m" at all.
