workstation/e101-*: 1c+ videodriver choice

I've shipped modesetting-based images and mga2-based ones (and reverted to modesetting by hand "when it MUST work"); let's just do it right. NB: found out that Name fields must NOT contain ";" or alterator-apt chokes in runtime (not fatal but still spectacular, see #35526).
