Some bluetooth implementations write to bluetooth.* properties.
It seems reasonable to allow this for all bluetooth implementations.
This addresses the following denial (seen on mako):
<4>[ 132.182755] avc: denied { set } for property=bluetooth.hciattach scontext=u:r:bluetooth:s0 tcontext=u:object_r:bluetooth_prop:s0 tclass=property_service
