Warn on multiple inclusion of RULES_BUILD

Browse Source 
RULES_BUILD has long had a multi-inclusion guard, but I want to
be able to remove it. This commit cleans up the current place where
it was happening, and shows a warning if the guard gets triggered,
but it doesn't stop builds from working if it happens.
