prevent loading of signed kernel modules:

Add policy changes to enable a new service. The service
is currently switched off in config, but this change is
needed before it could be enabled.

With project Treble, we're relying heavily on attributes for
permission inheritance and enforcement of separation between
platform and vendor components.
We neead tests that verify those attributes are correctly applied.
This change adds the framework for those tests including a wrapper
around libsepol for loading and querying policy, and a python module
for running tests on policy and file_contexts.
Included with the testing framework is a test asserting that the
coredomain attribute is only applied to core processes. This
verification is done using the following rules:
1. Domain's entrypoint is on /system - coredomain
2. Domain's entrypoint is on /vendor - not coredomain
3. Domain belongs to a whitelist of known coredomains - coredomain
In a subsequent commit these tests will be applied at build time.
However, I first need to fix existing Treble violations exposed by
this test. These tests will also be applied during CTS.

tombstoned allows dumpstate to install "intercepts" to java trace
requests for a given process. When an "intercept" is installed, all
trace output is redirected to a pipe provided by dumpstate instead
of the default location (usually in /data/anr or /data/tombstone).
Note that these processes are already granted "write" and "getattr"
on dumpstate:fifo_file in order to communicate with dumpstate; this
change adds "append" to the existing set of permissions.

Applications connect to tombstoned via a unix domain socket and request
an open FD to which they can write their traces. This socket has a new
label (tombstoned_java_trace_socket) and appdomain and system_server are
given permissions to connect and write to it.
Apps no longer need permissions to open files under /data/anr/ and
these permissions will be withdrawn in a future change.
