A default value of persist.sys.sf.native_mode could be set by SoC
partners in some devices including some pixels.
So it should have vendor_init_settable accessibility.

The netutils_wrapper is a process used by vendor code to update the
iptable rules on devices. When it update the rules for a specific chain.
The iptable module will reload the whole chain with the new rule. So
even the netutils_wrapper do not need to add any rules related to xt_bpf
module, it will still reloading the existing iptables rules about xt_bpf
module and need pass through the selinux check again when the rules are
reloading. So we have to grant it the permission to reuse the pinned
program in fs_bpf when it modifies the corresponding iptables chain so
the vendor module will not crash anymore.

Test: device boot and no more denials from netutils_wrapper

(cherry picked from commit 886aa54b)

The kernel generates file creation audits when O_CREAT is passed even
if the file already exists - which it always does in the cgroup cases.

We add neverallow rules to prevent mistakenly allowing unnecessary
create access. We also suppress these denials, which just add noise to
the log, for the more common culprits.

In permissive mode we get more spurious denials when O_CREAT is used
with an already-existing file. They're harmless so we don't need to
audit them.

Example denials:
denied { add_name } for name="trigger" scontext=u:r:init:s0 tcontext=u:object_r:sysfs_leds:s0 tclass=dir permissive=1
denied { create } for name="trigger" scontext=u:r:init:s0 tcontext=u:object_r:sysfs_leds:s0 tclass=file permissive=1

Verify that the SELabels used in property_contexts correspond to a
real type in the SEPolicy and that this type has the property_type attribute.

odm property_contexts doesn't duplicate either plat or vendor
property_contexts.

This allows an optimization that consists in the "perfetto" cmdline
client passing directly the file descriptor for the output trace
to traced (as opposite to having traced streaming back the trace
data to "perfetto" and having that one doing the write() into file).
This reduces sensibly the memory traffic and CPU overhead of traces
with a minor change.
