Motivation for this change

Certain kodi plugins that you can install imperatively from within kodi itself have python dependencies which must be in PYTHONPATH. For example, the plugin.video.netflix plugin requires pycryptodomex. Sure, this PR may be considered a tiny bit hacky, but I thought pushing these python dependencies into kodi via the plugins directive seemed reasonable 🤷‍♂️

kodi.override { plugins = with kodiPlugins; [ python2Packages.pycryptodomex ]; }'

Without this PR I have to hack in the extraRuntimeDependencies like so:

kodi.override { plugins = with kodiPlugins; [ (python2Packages.pycryptodomex // { extraRuntimeDependencies = []; }) ]; }'
