Let shell and bugreport read logging related properties.

Currently ro.device_owner and persist.logd.security aren't accessible
without root, so "adb shell getprop" returns empty reply which is
confusing. Also these properties aren't seen from bugreport unless
their change happened recently.

Bug: 37053313
Test: manual, took bugreport and ran getprop after "adb unroot".
