Sub directories under /odm (or /vendor/odm when there isn't an odm
partition) are labeled so that artifacts under the sub directories are
treated the same as their counterpart in the vendor partition.

For example, /odm/app/* is labeled as vendor_app_file just like
/vendor/app/*.

With the new patches backported to 4.9 kernels, the bpf file system now
take the same file open flag as bpf_obj_get. So system server now need
read permission only for both bpf map and fs_bpf since we do not need
system server to edit the map. Also, the netd will always pass stdin
stdout fd to the process forked by it and do allow it will cause the
fork and execev fail. We just allow it pass the fd to bpfloader for now
until we have a better option.

Test: bpfloader start successful on devices with 4.9 kernel.

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.

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.
