Remove netd access to sysfs_type attribute.

These were moved from vendor to fwk policy:
1. sysfs_net type declaration
2. labeling of /sys/devices/virtual/net with sysfs_net
3. netd access to sysfs_net

As part of Treble, enforce that the communication between platform
and vendor components use the official hw binder APIs. Prevent sharing
of data by file path. Platform and vendor components may share
files, but only via FD passed over hw binder.

violating domains that need to be fixed.

This change allows wpantund to call any binder callbacks that have
been registered with it. Generally, only privileged apps are allowed
to register callbacks with wpantund, so we are limiting the scope for
callbacks to only privileged apps. We also add shell to allow the
command-line utility `lowpanctl` to work properly from `adb shell`.
