Make __memcpy_avx512_no_vzeroupper an alias

Since x86-64 memcpy-avx512-no-vzeroupper.S implements memmove, make
__memcpy_avx512_no_vzeroupper an alias of __memmove_avx512_no_vzeroupper
to reduce code size of libc.so.

	* sysdeps/x86_64/multiarch/Makefile (sysdep_routines): Remove
	memcpy-avx512-no-vzeroupper.
	* sysdeps/x86_64/multiarch/memcpy-avx512-no-vzeroupper.S: Renamed
	to ...
	* sysdeps/x86_64/multiarch/memmove-avx512-no-vzeroupper.S: This.
	(MEMCPY): Don't define.
	(MEMCPY_CHK): Likewise.
