Browser VM shortcuts dont work and browsers may not be installed

[lozaning]

Pentoo - shortcut to the browser doesnt work from desktop, chrome opened manually still works
Parrot - no browsers appear to be installed at all
BlackArch - no browsers appear to be installed at all
Kali - for once actually is the one that works without issue.

Parrot and BlackArch will now have firefox installed. Kali and Pentoo already had it.

Remaining issue: the shortcut in pentoo doesn't work

The pentoo issue is that chrome gets picked as the default browser and it can't run as root without --no-sandbox being passed. I think the right solution here is to just remove chrome and have only firefox like all the other containers, but we actually use the main pentoo meta-packages which currently require chromium. I'll think on this and fix it somehow.
