[Buildroot] [git commit branch/2020.02.x] package/python-iptables: add explicit dependency on dynamic libs

commit: https://git.buildroot.net/buildroot/commit/?id=b6d45c45cb0e0e0a7080350dadb2eccefdaa8b0f
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2020.02.x

The package uses ctypes.CDLL extensively which only makes sense when dynamic
libraries are available.
