[PATCH v3 17/21] objtool/klp: Don't correlate arm64 mapping symbols

[Josh Poimboeuf <jpoimboe@kernel.org>]

ARM64 ELF files contain mapping symbols ($d, $x, $a, etc.) which mark
transitions between code and data.  There are thousands of them per
object file, all sharing the same few names.

They aren't "real" symbols so there's no need to correlate them.
