x86-64: Test memmove_chk and memset_chk only in libc.so [BZ #21741]

Since there are no multiarch versions of memmove_chk and memset_chk,
test multiarch versions of memmove_chk and memset_chk only in libc.so.

	[BZ #21741]
	* sysdeps/x86_64/multiarch/ifunc-impl-list.c
	(__libc_ifunc_impl_list): Test memmove_chk and memset_chk only
	in libc.so.
