tools arch: Update arch/x86/lib/memcpy_64.S copy used in 'perf bench mem memcpy'
To bring in the change made in this cset:
b69656fa7ea2 ("x86/uaccess: Fix up the fixup")
Silencing this perf build warning:
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
No changes in the tooling using this, that was just to ease some objtool
return checking.
