[PATCH] tools/testing/selftests/mm: add missing .gitignore entries

["Lorenzo Stoakes (ARM)" <ljs@kernel.org>]

Commit 2bee308f3adb ("selftests/mm: use pattern matching in .gitignore")
switched to a pattern-matching mechanism to reduce churn in .gitignore.

It however accidentally excluded the page_frag test's-generated module
intermediate C file with .mod.c extension, and also the local_config.h
header generated if liburing is available locally.

Explicitly fix both the issues, fixing the module-generated C file as a
general pattern as these are always intermediate files that should be
ignored.

Since this is a trivial .gitignore change it doesn't seem necessary to
treat it as a hotfix.
