lib/glob: convert selftest to KUnit

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