osmo-release.sh: Add check to make sure dependency requirements in configure.ac and debian/control match
So today while issuing a release for most osmocom CNI stuff, I ended up finding that while I was updating configure requirements by manually attempting builds (eg.
PKG_CHECK_MODULES(LIBOSMOCORE, libosmocore >= 1.2.0)), I forgot to update similar lines in debian/control(eg.
libosmocore-dev (>= 1.2.0),).
That's bad. Let's add some checks to make sure that changes in configure.ac are matched in debian/control.
It should be enough for osmocom libraries, not needed for all dependencies.
Also make sure all osmocom dependencies under debian/control of all projects have dependency requirements set (the >= x.y.z part set).
What's described in the original ticket is implemented here: https://gerrit.osmocom.org/c/libosmocore/+/15110
Another feature is needed: Make sure that $GIT_DIR/$project/debian/patches/build-for-debian8.patch can be applied (if file exists). If applying patch fails, abort release.
