content_permissions.xml: container type needs to be part of all type to access settings provider

Otherwise applications of the container domain will fail to access the settings provider
with the default settings (use:r) and can't start:

D/ContentSecurityManager(  401):

name":"org.scforandroid.TestContainerApp"},"access":"USE","decision":"false","destination":{"package":"com.android.providers.settings","uid":"1000","authority":"settings","public
name":"com.android.providers.settings.SettingsProvider","type":"settings_provider","process
name":"com.android.providers.settings.SettingsProvider"}}
