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

This is to get the changes from:

  94ea9c05219518ef ("x86/headers: Replace #include <asm/export.h> with #include <linux/export.h>")
  10f4c9b9a33b7df0 ("x86/asm: Fix build of UML with KASAN")

That addresses these perf tools build warning:

  Warning: Kernel ABI header differences:

    diff -u tools/arch/x86/lib/memset_64.S arch/x86/lib/memset_64.S
