Suspend newly installed apps when personal apps are suspended

Also make use of PackageManager.getUnsuspendablePackages() which
already takes care of launcher and dialer packages and some
other critical apps, like package verifier, package
[un-]installer, etc.

For newly installed packages it PackageManager.getUnsuspendableApps()
seems to be sufficient since that app won't be critical for the
functioning of the device.
