No, that's just how rauc works, there's no other use case. That is, it
always make a signed squashfs image (there's no option to make
unsigned images or any other format). If mksquashfs isn't present, the
host tool is effectively useless since it can't make bundles, that's
why I feel that it's a run-time dependency and needs to be selected.
