Update .deb to use dh_missing
While building .deb for libosmocore following warning was observed:
sed -i "/dependency_libs/ s/'.*'/''/" `find . -name '*.la'` dh_install dh_install: Please use dh_missing --list-missing/--fail-missing instead dh_install: This feature will be removed in compat 12.
We should follow this recommendation and update our packaging before compat 12 becomes mainstream. We should also check other Osmocom .deb packages because they might have similar issues.
