Cleanup dependency handling
Always try to gather all compressor libraries available, but only
complain about missing a one if it has been *explicitly* selected.
If a compressor has been explicityl disabled, we can still turn it
off after checking.
Also, rework gensquashfs to set the default compressor based on
what's available.
