[lld-macho] Don't emit rebase opcodes for subtractor minuend relocs

Also add a few asserts to verify that we are indeed handling an
UNSIGNED relocation as the minued. I haven't made it an actual
user-facing error since I don't think llvm-mc is capable of generating
SUBTRACTOR relocations without an associated UNSIGNED.
