libpayload: Support unaligned pointer for memcpy, memmove and memcmp

The memcpy(), memmove() and memcmp() functions use word by word
operations regardless of the pointer alignment.  Depending on the
platform, this could lead to a crash.

This patch makes the memcpy(), memmove() or memcmp() operate byte per
byte if they are supplied with unaligned pointers.
