microdroid_manager needs to know its own CID until the full RPC binder
support is landed.

With a change in dex2oat to avoid opening /proc/self/fd, this change
removes open and a few other privileges from dex2oat.

CAP_SYS_ADMIN is required to mount a filesystem (currently in authfs, a
child process of authfs_service). It seems the parent also needs to be
allowed.

Test: Use the service (from compsvc), no longer seeing the denials

Microdroid_manager creates a vsock socket and app's output is redirected
to it.

authfs_service is a binder service on microdroid. Upon a request by the
client, the service will create the mount directory, execute authfs to
mount the FUSE, and finally unmount and delete the mount directory.
authfs currently requires more privileges than it should, but it's ok
because the client owns the VM, and all input will be verified by
signatures. But there is plan to keep the privileges isoated in the
service (b/195554831).

Test: Start the service from init, use a test executable to call the
service API. Only observed denial from the test executable.

Microdroid_manager should verify payloads(APK/APEXes). APK is mounted to
dm_device first and then verified. So, microdroid_manager needs to read
it.

This is the only blocker for SELinux denial test on microdroid. Rather
than consuming more time, this temporarily suppresses the audit message
to turn on the test.

keystore uses sqlite3. sqlite3 calls F2FS_IOC_GET_FEATURES. As
microdroid has nothing to do with that, we just suppress the audit.

It's a test tool which is generally run as root, and will be deleted
eventually. It doesn't need its own label; system_file works fine.
We never actually allowed it anything, nor defined a transition into
the domain.

microdroid_payload attribute is for processes meant to be run by
microdroid_manager as a payload. Other than microdroid_payload and
crash_dump, transition from microdroid_manager will not be permitted.

This is necessary (but not sufficient) to allow CompOsTestCase to
run. Without it we have problems because
system/sepolicy/apex/com.android.art-file_contexts references
dex2oat_exec, and we get an error:
SELinux : Context u:object_r:dex2oat_exec:s0 is not valid (left unmapped).
