selftests/mm: rename hugepage-* tests to hugetlb-*

hugepage could mean both THP and HugeTLB these days.

Rename hugepage-* tests for HugeTLB to hugetlb-* to avoid confusion.

Make sure that Makefile update keeps alphabetical ordering of the
TEST_GEN_FILES entries.

Keep old binary names in .gitignore because Linus prefers it this way.
