tools headers: Update the copy of x86's memcpy_64.S used in 'perf bench'

We also need to add SYM_TYPED_FUNC_START() to util/include/linux/linkage.h
and update tools/perf/check_headers.sh to ignore the include cfi_types.h
line when checking if the kernel original files drifted from the copies
we carry.

This is to get the changes from:

  ccace936eec7b805 ("x86: Add types to indirectly called assembly functions")

Addressing these tools/perf build warnings:

  Warning: Kernel ABI header at 'tools/arch/x86/lib/memcpy_64.S' differs from latest version at 'arch/x86/lib/memcpy_64.S'
  diff -u tools/arch/x86/lib/memcpy_64.S arch/x86/lib/memcpy_64.S
