Restrictions introduced in vendor init mean that new devices
may not no longer exempt vendor init from writing to system_data_file.
This means we must introduce a new label for /data/vendor which
vendor_init may write to.

Instead of having statsd linking the perfetto client library
and talk directly to its socket, we let just statsd exec()
the /system/bin/perfetto cmdline client.
There are two reasons for this:
1) Simplify the interaction between statsd and perfetto, reduce
dependencies, binary size bloat and isolate faults.
2) The cmdline client also takes care of handing the trace to
Dropbox. This allows to expose the binder interaction surface
to the short-lived cmdline client and avoid to grant binder
access to the perfetto traced daemon.
This cmdline client will be used by:
- statsd
- the shell user (for our UI and Studio)
