Alex Klyubin 6fe344e350 Remove hal_gatekeeper from gatekeeperd domain
HAL clients should not be annotated with hal_x and haldomain. This may
grant them too much access. Instead, the policy needed for using
in-process HALs should be directly embedded into the client's domain
rules.

This partially reverts the moving of rules out of gatekeeperd in
commit a9ce208680.

Test: Set up PIN-protected secure lock screen, unlock screen, reboot,
      unlock. No SELinux denials in gatekeeperd or hal_gatekeeper*.
