pv: Honour test_wants_user_mappings

32bit PV guests start on supervisor mappings, and previously unilaterally
switched to user mappings.  Now, only switch to user mappings if a test has
opted in.

64bit PV guests run at cpl3, must use user mappings and architecturally have
no choice in the matter.

This change is best reviewed with `git show --ignore-all-space`
