main/aports-build: refactor plugins

plugins was refactored in lua-aports-1.0.0 so configuration and plugin
code are separate. Plugins now goes to /usr/share/buildrepo/plugins and
config are in /etc/buildrepo/config.lua.

This makes it much easier to update the plugin code without manually
edit the config on each builder.
