AArch64: Avoid memset ifunc in cpu-features.c [BZ #33112]

During early startup memcpy or memset must not be called since many targets
use ifuncs for them which won't be initialized yet.  Security hardening may
use -ftrivial-auto-var-init=zero which inserts calls to memset.  Redirect
memset to memset_generic by including dl-symbol-redir-ifunc.h in cpu-features.c.
This fixes BZ #33112.
