0.22.x: missing soversion in e.g. libpman.so, though libpman.pc claims it has #2696
Description
Describe the bug
I'm working on making falcosecurity-libs a standalone package (with shared libs) on Gentoo and just tried 0.22.0. Practically everything worked fine 🎉 except that - when enabled - libpman.so has no version number
How to reproduce it
Build libs with support for the modern bpf probe, which should build libpman.
Expected behaviour
libpman.so with shared lib versions, like the other libs.
Environment
Gentoo Linux, but any supported Linux should do.
