Description:
If collectd configuration loads python plugin, collectd does not start with error:
```
dlopen("/usr/lib/collectd/python.so") failed: /usr/lib/collectd/python.so: undefined symbol: PySys_SetArgv. The most common cause for this problem is missing dependencies. Use ldd(1) to check the dependencies of the plugin / shared object.
plugin_load: Load plugin "python" failed with status 2.
```

Somehow collectd plugin even is not linked with python:
$ ldd /usr/lib/collectd/python.so |grep --count python
0

For comparison in collectd 5.9.0-1:
# ldd /usr/lib/collectd/python.so | grep python
libpython3.7m.so.1.0 => /usr/lib/libpython3.7m.so.1.0 (0x00007f3912d6d000)

Additional info:
collectd 5.9.2-3
