CI: Disable ZIP file artifacts, update versions

The GH artifacts action now lets you disable auto-zipping your
artifacts.  Previously, GH would always automatically put your
artifacts in a ZIP file.  This is annoying when your artifacts
are already in a tarball.

Also update the following action versions

checkout:		v4 -> v6
upload-artifact:	v4 -> v7
download-artifact:	v4 -> v8

Lastly, fix a issue where zfs-qmeu-packages now needs to power
cycle the VM.
