build: Set a SONAME version in the libraries

The libraries built are currently unversioned, but donwstream users expect
these to have a proper SONAME version in order to package them. Most Linux
distributions packaging guidelines for example have this as a requirement.

There are alredy released versions and git tags, so let's use those as the
libraries version, and the major number as the SONAME version. This is the
convention used by most projects.
