Wipe permissions using Mozilla API

Mozilla accepted our patch from legacy/trac#2950 (closed) (a pref to make Permissions manager DB memory-only), with the restriction that the pref, "permissions.memory_only" be read only at startup. In torbutton, we use the pref at runtime, but this is unnecessary. To wipe permissions, we can call Services.perms.removeAll();

r=mcs. If I remember correctly, at the dev meeting on Monday you concluded that this cleared the in-memory permissions synchronously and that is sufficient because the info on disk is only read at startup.

Yep. Merged and pushed.
