batman-adv: upgrade package to latest release 2021.0

* support latest kernels (4.4 - 5.11)
* coding style cleanups and refactoring
* drop support for sysfs+debugfs
* allow to select routing algorithm during creation of interface
* bugs squashed:

  - allocate enough reserved room on fragments for lower devices
