Use lower-level SetInactiveFlag to disable account

Rely on the Gerrit lower-level interface to disable accounts
so that users can be allowed to self-disable themselves.

Access to self-removal is however protected by a new permission
provided by this plugin. Skipping thus the self-disabling
check in Gerrit is considered safe in this case.
