edsp: drop privileges before executing solvers
Most (if not all) solvers should be able to run perfectly fine without root privileges as they get the entire state they are supposed to work on via stdin and do not perform any action directly, but just pass suggestions on via stdout. The new default is to run them all as _apt hence, but each solver can configure another user if it chooses/must. The security benefits are minimal at best, but it helps preventing silly mistakes (see 35f3ed061f10a25a3fb28bc988fddbb976344c4d) and that is always good. Note that our 'apt' and 'dump' solver already dropped privileges if they had them.
