Add hwservice_contexts and support for querying it.
hwservicemanager can check hwservice_contexts files
both from the framework and vendor partitions.
Initially, have a wildcard '*' in hwservice_contexts
that maps to a label that can be added/found from
domain. This needs to be removed when the proper policy
is in place.
Also, grant su/shell access to hwservicemanager list
operations, so tools like 'lshal' continue to work.
