pmbootstrap qemu: fix depends / no progress bar for --details-to-stdout

pmbootstrap qemu is currently broken, because the qemu package in Alpine has been split up into more packages, and pmbootstrap doesn't install all of the now required ones before trying to run qemu. The fist two patches fix this. This fix is important, so I'll make a new pmbootstrap release with it once CI passes.

Since the new release will also contain the recently added apk progress bars, I've included another patch to disable them when using --details-to-stdout, because it messes up the output otherwise.

All three patches are fairly trivial, so I'll just merge them when CI passes.
