paho-mqtt-cpp: pass static/shared build to cmake

Allows to build paho-mqtt-cpp with pkgsStatic,
which results in the following build failure without this change:
```console
$ nix build ".#paho-mqtt-cpp"
error: builder for '/nix/store/hppw8cjha4qkvxl3670886rm4i2q0mi0-paho.mqtt.cpp-static-x86_64-unknown-linux-musl-1.3.2.drv' failed with exit code 2;
