We don't want the version of the last tagged version, but the version
number uniquely representing the current HEAD. Use the script from
libosmocore.
I suspect that this somehow got broken in commit 00d5114717

Latest tag 0.3.0 was created in a release branch instead of master. As a
result, git describe doesn't show them. Let's instead reuse git command used in
osmo-ci to get latest tag from tag list when OBS latest repository is
built.

In AC_INIT(), it still stated openbts. Let's clean this up and use
the same method of version generation that we use in all other osmocom
projects, too.
