liblwgeom has separate packages because that's how libraries are
commonly packaged in Debian. The library package name matches the
library SONAME (liblwgeom-2.1.8.so), and changes every time the SONAME does.

liblwgeom should move to a stable SONAME like liblwgeom.so.2 that only
changes when the ABI breaks, e.g. using `libtool -version-info`.
