Make fallback MD5 implementation thread-safe on big-endian systems

Replace a static scratch buffer with a local variable, because a
static buffer makes the function not thread-safe. This function is
used in client-code in libpq, so it needs to be thread-safe. It was
until commit b67b57a966, which replaced the implementation with the
one from pgcrypto.

Backpatch to v14, where we switched to the new implementation.
