Don't use pointers to the low byte of multi-byte integers

This only works on little endian systems (which is all we support currently).

Fixes CID 174261: Wrong size argument

This binary drop file writing code is pretty terrible and inefficient, but I remember being really proud of it (supporting so many drop files). This really should be re-written to use structures and/or buffered file I/O.
