session: Add virtboard to session
Adds virtboard to required components of the session.
This should go in after https://source.puri.sm/Librem5/virtboard/merge_requests/13
It will work better after https://source.puri.sm/Librem5/phosh/issues/44 is solved.
Even better when https://source.puri.sm/Librem5/virtboard/merge_requests/17 goes in.
