ifdtool: avoid potential unaligned pointer usage
In get_region, ifdtool assigns a not-known-to-be-aligned
pointer to a uint32_t *. Now you know and I know that it is
almost certainly aligned, but clang on OSX doesn't like this,
and it's a dicey thing to do in any event, just waiting
to hit someone hard at some future date.
Assign the pointer to a void * and use memmove to copy
the value to a uint32_t.
This usage is more portable to all little-endian architectures,
now, but is still not endian-safe. I doubt we'll ever care.
