[yabridgectl] Show VST2 library architecture

Just like it already did for the VST3 library. This information was not
necessary for the functionality of yabridgectl, but it does look nicer
this way.

   once after updating to yabridge 4.0, yabridge can now be updated without
   needing to rerun `yabridgectl sync`. This is particularly useful when using a
   distro packaged version of yabridge.
+- `yabridgectl status` now lists the architecture of
+  `libyabridge-chainloader-vst2.so` just like it already did for the VST3
+  library.
