The current selftests/mm/.gitignore hardcodes each generated test binary
by name, which requires manual updates every time a new test is added.

This series switches to a pattern-matching approach (similar to KVM
selftests), ignoring everything by default and allowing specific source
extensions. To accommodate this without tracking generated headers,
local_config.h is renamed to local_config.h_gen.

Changelog since v2:
- Split the changes into two separate patches (header rename and
  .gitignore update)
- Added Suggested-by for David Hildenbrand for the header rename approach.
- Dropped David's and Yosry's Reviewed-by tags.
- Kept Lorenzo Stoakes's Reviewed-by and added Mike Rapoport's Acked-by.

Changelog since v1 (RFC):
- Renamed local_config.h to local_config.h_gen to avoid conflict with !*.h.
- Updated Makefile, check_config.sh, and affected .c files for the rename.
- Removed *.mod.c as it was unnecessary.

Adding previous revision links together [1] would be helpful for people who
willing to see details of previous discussions.

So, after applying the first patch, we may show local_config.h unexpectedly
shown on 'git status' output?  Maybe too trivial thing, but I'm wondering if we
already considered doing the renaming first.
