Restore host list settings visibility in minimal blocking mode (#547)

The blocking mode feature (commit 6946906) hid manage_blocklists,
hosts_download, and hosts_auto_update preferences when in minimal mode.
Since minimal is the default mode, this made host list management
inaccessible. These settings should be visible in all blocking modes
so users can always add and manage multiple host lists.
