Allow LockScreenPattern to be launched in the pinning screen

If work profile lock is enabled and work app is pinned, users will get a
black/white screen on the phone. That's because Settings is prevented
from other apps launch any pages of Settings in the pinning mode.

In order to launch some pages of Settings from other apps, we add a
condition to the preventive mechanism and allow the activity inherited
from SettingsBaseActivity to override the condition to have the activity
to be launched from other apps in the pinning mode.
