scripts/kallsyms: move compiler-generated symbol patterns to mksysmap

scripts/kallsyms.c maintains compiler-generated symbols, but we end up
with something similar in scripts/mksysmap to avoid the "Inconsistent
kallsyms data" error. For example, commit c17a2538704f ("mksysmap: Fix
the mismatch of 'L0' symbols in System.map").

They were separately maintained prior to commit 94ff2f63d6a3 ("kbuild:
reuse mksysmap output for kallsyms").

Now that scripts/kallsyms.c parses the output of scripts/mksysmap,
it makes more sense to collect all the ignored patterns to mksysmap.
