package: cfgfs: Fix for ignored attribute warnings

The 'bounded' attribute seems to never have existed. Replace it by the
'access' attribute which probably does the same. Declare decompressors'
'dst' parameter as read_write for now, no idea if any of them reads back
the written output while decompressing.
