[PATCH] selftests/mm: add CONFIG_DEBUG_FS to the config fragment

[Sasha Levin]

The split_huge_page and gup tests need debugfs, and CONFIG_GUP_TEST
depends on it. Add CONFIG_DEBUG_FS=y to the fragment.

Merged into an x86_64 tinyconfig, the fragment leaves CONFIG_DEBUG_FS
and CONFIG_GUP_TEST unset without this change and sets both with it.
x86_64_defconfig already has CONFIG_DEBUG_FS=y and is unaffected.
