Screen-pinning unpin security fails for secondary user. DO NOT MERGE

The setting that inidcates that the user must unlock the device first
to unpin an app is always read for the owner user, so if the owner
disables this it will also be disabled for all secondary users no
matter what they have selected.

Bug: 64235463
Test: Manual
- Enable Screen-pinning for owner

- Create a secondary user
- Create keyguard PIN
- Enable screen-pinning for secondary user
- Check 'Ask for PIN when unpinning'
- Exit settings and start an app
- Pin the app from recents

The keyguard should appear on unpin with this commit applied
