Store package restriction settings at shutdown

Symptom:
Disabled package was re-enabled by restarting a device.

Root cause:
PMS postpones storing the package restriction settings in 10
seconds by design. When a package gets disabled right before
shutdown, PMS fails to store the last changes.

Solution:
Store package restriction settings at shutdown.
