[PATCH 4/4] selftest/arm64: Add MTE test config fragment

[Muhammad Usama Anjum]

The arm64 selftest collection has no Kconfig fragment, so kernels built
with the selftest requirements are not guaranteed to provide the support
used by the MTE tests.

Add a fragment covering the userspace MTE and tagged-address ABIs, KSM
and its sysfs interface, explicit HugeTLB mappings and their proc/sysctl
interfaces, and tmpfs-backed file mappings.

Do not request NUMA solely for the optional KSM merge_across_nodes.
