Disable privapp_permissions checking in GSI temporarily

Some vendor apps are using shared UID without white-listing the apps.
A runtime checking with these apps causes some devcies cannot boot
with GSI. We disable the checking before bug b/78105955 solved.

Test: Boot pixel devices with GSI applied the patch.
