Remodel file extraction tools to use libfstream

This commit rewrites the libtar write paths to use libfstream insead of
a FILE pointer. Also, the libcommon file extraction function is remodeled
to use libfstream.

In accordance, rdsquashfs, sqfs2tar and sqfsdiff have some minor
adjustments made to work with the ported libtar and libcommon.
