manuals: publish pyosmocom manuals for releases

Adjust the building and publishing commands to work for pyosmocom.
Remove the 0.0.3 release from TAGS_IGNORE, because it already has
manuals.

Skip "apt-get -y build-dep" and adjusting "debian/control" if that file
does not exist, as it is the case with the 0.0.3 and 0.0.4 releases of
pyosmocom.
