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 v3 [3]:
- Reordered the patches so that local_config.h is renamed before
  updating .gitignore, preventing local_config.h from temporarily
  showing up as an untracked file in git status (SeongJae Park).

Changelog since v2 [2]:
- 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) [1]:
- 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.
