[AArch64] Cleanup TLS relocation types which don't go through GOT table
This patch done two types of cleanup:
* in aarch64_reloc_got_type and elfNN_aarch64_relocate_section
We don't need those redundant "case" check, as they can be merged
with the "default" which just "break".
* in elfNN_aarch64_gc_sweep_hook and elfNN_aarch64_check_relocs
All TLS local executable relocations and some local dynamic
relocations (those calculate module offset) actually don't need GOT
entry, so remove them from GOT entry counting.

* elfnn-aarch64.c (aarch64_reloc_got_type): Delete useless check.
(elfNN_aarch64_relocate_section): Likewise.
(elfNN_aarch64_gc_sweep_hook): Likewise.
(elfNN_aarch64_check_relocs): Likewise.
