Subject: Extract OS component when using older ipsw archives

Older ipsw archives have the root filesystem stored in compressed
format rather than just "stored". The "Verifying Filesystem" step
would then fail as compressed files are not seekable in ZIP files.
This commit introduces a detection for this and has the filesystem
extracted should it be required.
If not using a cache path, the temp file used for extraction will
be deleted after the procedure is completed.
