These two selinux policy violations keep showing up from statsd's CTS
tests, although statsd and the CTS test seemed to function fine despite
them. Nonetheless, they seem reasonable to add to the list.

The previous selinux rules obtained via audit2allow didn't really
work with the case of apps connecting to the producer socket,
despite all the allow rules being correctly in place.
This was failing our CTS tests.

The reason for the failure (see denials pasted below) is due to
Multi Level Security (for multi-user), which was still preventing
apps form a different level to connect to the traced producer
socket and write to the shmem buffers they get passed back.
This CL tags the objects being accessed as mlstrusted.
CTS tests pass with this CL.

In this architecture, the system_server instructs the zygote to fork a
child-zygote to be the webview_zygote. The system_server tells this new
zygote to listen for fork requests on a random abstract unix socket of
its choosing.

A follow-up CL will remove the rules for starting webview_zygote via
init.

CTS tests need to be able to call, from hostside:
adb shell cmd stats dump-report (and others)
On a user build, this will fail because of an selinux policy violation
from shell. This cl fixes this by granting shell permission.

Similarly, Settings needs to communicate with statsd, so
system_app-statsd binder calls are given permission.

Allows the traced_probes daemon to access the core ftrace
functionalities on user builds. Specifically this involves:
- Whitelisting the per_cpu/ subdirectory to access:
  1) trace_pipe_raw file to allow perfetto to read the raw
     ftrace buffer (rather than the text-based /trace endpoint)
  2) cpuX/stats and cpuX/buffer_size_kb that allow to
     tune the buffer size per-cpu pipe and to get basic
     statistics about the ftrace buffer (#events, overruns)
- Whitelistiing the full event directories rather than the
  /enable files. This gives also access to the /format files
  for the events that are already enabled on user builds.
  /format files simply describe the memory layout
  of the binary logs. Example: https://ghostbin.com/paste/f8m4k

This still does NOT allow enabling the events labeled as
"_debug" (mostly events that return activity on inodes).
We'll deal with that separately as soon as we get a POC
of inode resolution and a sensible blacklist/whitelist model.

Since we now call patchoat --verify in zygote art loading code, we have
the unintended effect of webview zygote calling patchoat --verify. This
is undesireable since webview zygote doesn't need to verify the .art
files after the app_process zygote has already done so. The exec of
patchoat fails for webview zygote, and this change hides that. This
change should be reverted when b/72957399 is resolved.
