tools/nolibc: x86_64: use local label in memcpy/memmove
Compiling arch-x86_64.h with clang and binutils LD yields
duplicate label errors:
.../gcc-13.2.0-nolibc/x86_64-linux/bin/x86_64-linux-ld: error: LLVM gold plugin: <inline asm>:44:1: symbol '.Lbackward_copy' is already defined
.Lbackward_copy:leaq -1(%rdi, %rcx, 1), %rdi
Instead of a local symbol use a local label which can be defined
multiple times and therefore avoids the error.
