[PATCH nolibc 09/19] tools/nolibc: string: Remove the `_nolibc_memcpy_up()` function

[Paul E. McKenney]

From: Ammar Faizi <ammarfaizi2@xxxxxxxxxxx>

This function is only called by memcpy(), there is no real reason to
have this wrapper. Delete this function and move the code to memcpy()
directly.
