ELFObjectWriter: Disable STT_SECTION adjustment for .reloc
... to match GNU Assembler. This generalizes the
SHT_LLVM_CALL_GRAPH_PROFILE special case (which uses .reloc with
BFD_RELOC_NONE https://reviews.llvm.org/D104080).
Targets that want STT_SECTION adjustment cannot use
FirstLiteralRelocationKind derived fixup kinds.
Depends on the fix of #135521
