kselftest/arm64/mte: Add mtefar tests on check_mmap_options

If FEAT_MTE_TAGGED_FAR (Armv8.9) is supported, bits 63:60 of the fault address
are preserved in response to synchronous tag check faults (SEGV_MTESERR).

This patch adds new test cases using address tags (bits 63:60),
corresponding to each existing test in check_mmap_option.
