Add DISALLOW_APPS_CONTROL check into uninstall app for all users

Browse Source 
Settings App info page supports a "Uninstall for all users" function
when multiple users are enabled. It bypasses the restriction of
DISALLOW_APPS_CONTROL which breaks the user isolation guideline.

To fix this vulnerability, we should check the DISALLOW_APPS_CONTROL
restriction to provide the "Uninstall for all users" function.
