Allow dumpstate to dump face/fingerprint/gnss HALs

Seen with "adb bugreport" on cuttlefish:

avc: denied { call } for scontext=u:r:dumpstate:s0
  tcontext=u:r:hal_face_default:s0 tclass=binder permissive=0
avc: denied { call } for scontext=u:r:dumpstate:s0
  tcontext=u:r:hal_fingerprint_default:s0 tclass=binder permissive=0
avc: denied { call } for scontext=u:r:dumpstate:s0
  tcontext=u:r:hal_gnss_default:s0 tclass=binder permissive=0

Fix it like aosp/1313514
