x86-64: Optimize L(between_2_3) in memcmp-avx2-movbe.S

Turn

movzbl -1(%rdi, %rdx), %edi
movzbl -1(%rsi, %rdx), %esi
orl %edi, %eax
orl %esi, %ecx

into

movb -1(%rdi, %rdx), %al
movb -1(%rsi, %rdx), %cl

* sysdeps/x86_64/multiarch/memcmp-avx2-movbe.S (between_2_3):
Replace movzbl and orl with movb.
