[PATCH 1/4] selftest/arm64: Print TAP header

[Muhammad Usama Anjum <usama.anjum@arm.com>]

The test sets a TAP plan and emits a result but does not print the TAP
version header. Direct execution therefore starts with:

  1..1

instead of "TAP version 13", leaving the output malformed for TAP
consumers.

Print the kselftest header before the plan, matching the other arm64 MTE
tests.
