system_api: Support for temporary policy read
This contains two changes:
- Protobuf change in cryptohome to allow temporary user home mounts and
return their location.
- New method in login_manager to read policy from a temporary user home
mount.
Both changes are required to read user policy before actual cryptohome
mount, which will be necessary to decide if ext4 migration is allowed.
