selftests/mm: rename local_config.h to local_config.h_gen

Patch series "selftests/mm: use pattern matching in .gitignore", v4.

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.


This patch (of 2):

Because local_config.h is a generated build artifact, un-ignoring all .h
files in .gitignore causes it to incorrectly show up as an untracked file
in git status.

Rename it to local_config.h_gen so it no longer matches the !*.h inclusion
rule, preparing for a subsequent patch that switches .gitignore to a
pattern-matching approach.

Update Makefile, check_config.sh, and affected test sources (cow.c,
gup_longterm.c) accordingly.
