Using blueprint.Rule for protoc commands was causing code duplication because there was no good way to run the same protoc for cc, java and python but then run custom source packaging steps for java and python. Move most of the code into a common function that returns a RuleBuilder, and then let java and python add their own commands at the end of the rule.
