drop lxc dependency, as apk detects the lxc-libs dep and the init
script creates the required directory itself.

fix the init script: when the container manager failed, the openRC
service wasn't able to start. It could not be started again because
anbox-bridge.sh errored out: it was unable to create an already
existing interface.

this allows removing /var/lib/anbox while anbox is stopped to do
a "factory reset"

this allow plasma mobile and phosh to use the icon, and make the anbox-launch script fixes useful.

* give even more time to start, because Android is visibly quite
  long to start on a phone
* backport the input chmod patch, it unbreaks touch input on some
  devices
* ignore wayland env vars, as they aren't actually working

Due to an accidental force push, the commits for these packages were rewritten.
Make sure they are rebuilt so that the commit hash matches what's in aports.

This commit upgrades to 3rd march master, and address the following:

 * repair and enable unit tests.

 * add icon.

 * drop arm build patch as it was merged upstream.

 * drop armhf architecture as there is no android image anyway for
   this arch.

 * drop -networkmanager subpackage: it isn't needed anymore as the
   iptable script requirement are better known.

* remove files from a dependency that got installed to
  `/usr/include` and similar, as they don't belong to the package
  (it probably should be removed and split to another package altogether).

 * add root shell script.
