[PATCH v4 1/2] selftests/mm: rename local_config.h to local_config.h_gen

[pratmal@google.com]

From: Pratyush Mallick <pratmal@google.com>

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.
