Breaking ABI change

[mamins1376]

Installing on Void, a linking error happens (issue void-linux/void-packages#20618).

$ wf-background
wf-background: symbol lookup error: wf-background: undefined symbol: _ZN12wf_animation6circleE

According to @xtraeme, WayfireWM/wf-config@211a86c caused that.

$ ldd -r `which wf-background`

You just need to update wf-config. We require version 0.4 with latest wf-shell.

I don't think wf-config uses a .so name, plus meson.build clearly says it requires wf-config >= 0.4

That being said, soname would be a good idea, but this is an issue in wf-config, not wf-shell (please open an issur there). Closing this one.
