tools/lib/mm: move hugepage_settings out of selftests

Move hugepage_settings.[ch] from tools/testing/selftests/mm/ to
tools/lib/mm/ so the THP and HugeTLB helpers can be shared more easily
between selftests and other tools.

Keep the helpers exposed to mm selftests through vm_util.h where possible,
and use direct <mm/hugepage_settings.h> includes for files that do not
include vm_util.h.  Adjust the selftests/mm build to compile the moved
implementation from its new location.

Remove the remaining kselftest dependency by including file_utils.h
directly and using EXIT_FAILURE in the signal handler.
