Change Big Endian backup implementations to use signed indexes

load64() counted down from 7..0, but the decrement turned 0 into 255.
This means the loop would never terminate on Big Endian systems.

Just use signed char integers since we're only dealing with values from 0..7 anyway.

Closes https://bugs.php.net/bug.php?id=73282
