anjiahao 7f5f0f5e53 libs/libc/string: Fix asrc alignment for unaligned access in memrchr. 
memrchr scans backward, so the original implementation aligned
(x + 1) rather than x:

  #define UNALIGNED(x) ((long)(uintptr_t)((x) + 1) & (sizeof(long) - 1))

while the common UNALIGNED_X() macro checks the pointer itself.  Pass
src0 + 1 to UNALIGNED_X() to restore the original behavior, otherwise
asrc is off by one byte and the word loop reads the wrong data.
