CBFS: Use memmove instead of memcpy when loading a file from CBFS.
It might be the case that a file is being loaded from a portion of CBFS which
has already been loaded into a limitted bit of memory somewhere, and we want
to load that file in place, effectively, so that it's original location in
CBFS overlaps with its new location. That's only guaranteed to work if you use
memmove instead of memcpy.
