Set IMALISON_SESSION_TYPE env var for reliable X11/Wayland detection

Browse Source 
systemd user environment persists across login sessions, so
XDG_SESSION_TYPE can be stale. Proactively set a custom variable
on each session start so ConditionEnvironment checks are reliable.

Use it for xsettingsd and random-background (X11-only services).
