Don't comment out the pdf glob, it works as intended when building the
package on OBS. I had disabled it, because with dpkg-buildpackage,
override_dh_auto_configure from debian/ruls gets ignored, leading to
--enable-manuals missing in ./configure, and to the pdf file not being
present. But apparently, dpkg-buildpackage just always ignores this,
it's the same with other Osmocom repositories.

Adjust the build system, packaging etc. to split osmo-gbproxy into its
own git repository. Remove tests and configs that aren't related to
osmo-gbproxy.
