tools headers: Update the copy of x86's mem{cpy,set}_64.S used in 'perf bench'

Also add SYM_PIC_ALIAS() to tools/perf/util/include/linux/linkage.h.

This is to get the changes from:

  419cbaf6a56a6e4b ("x86/boot: Add a bunch of PIC aliases")

That addresses these perf tools build warning:

  Warning: Kernel ABI header differences:
    diff -u tools/arch/x86/lib/memcpy_64.S arch/x86/lib/memcpy_64.S
    diff -u tools/arch/x86/lib/memset_64.S arch/x86/lib/memset_64.S
