Add binary-only package for sbts2050-util

sbts2050-util is a small binary-only userspace program used to
interface with the sysmoBTS 2050 board management controller,
i.e. to enable/disable PA power, read power consumption/temperature
and the like.

This tool is going to disappear once the respective features have been
included in the (open source) sysmobts-util / sysmobts-mgr.  Please be
patient meanwhile.
