Bug 20415: Remove UseKohaPlugins system preference

I don't think the system preference adds any security. There are already multiple permissions required for working with plugins:

- Configure plugins
- Manage plugins ( install / uninstall )
- Use report plugins
- Use tool plugins

And even with those permissions your server must be configured to allow the use of plugins.

Test plan :
1) Install kitchen sink plugin https://github.com/bywatersolutions/koha-plugin-kitchen-sink
2) Run misc/devel/install_plugins.pl
3) Set config enable_plugins=1
4) Check all parts of the plugin are working
5) Set config enable_plugins=0
6) Check all parts of the plugin are disabled
