Don't put SSE2/AVX/AVX512 memmove/memset in ld.so
Since memmove and memset in ld.so don't use IFUNC, don't put SSE2, AVX and AVX512 memmove and memset in ld.so. * sysdeps/x86_64/multiarch/memmove-avx-unaligned-erms.S: Skip if not in libc. * sysdeps/x86_64/multiarch/memmove-avx512-unaligned-erms.S: Likewise. * sysdeps/x86_64/multiarch/memset-avx2-unaligned-erms.S: Likewise. * sysdeps/x86_64/multiarch/memset-avx512-unaligned-erms.S: Likewise.
