Pass "-g --user all" when installing apps (3/n)

'-g' to grant permissions automatically without checking the API level.
This works around the issue of b/149733368#comment2.

'--user all' to install the app on all users. This is more efficient
than calling #installPackageAsUser one by one on each user.
