update_engine: Don't search for deflates again in SquashFS compressed files

When we initialize a SquashFS file system, at the same time we find the
location of all deflate buffers. But for some files that have specific
postfix like gz or zip, we try to find the deflates there again. But, we
should only do this when the SquashFS did not actually compress that
file. Otherwise we're just gonna fail.
