Add javax.inject as direct dependency

Since the javax.inject.Provider interface is imported and used in every constructor of the *QueryFactory classes ( example at https://github.com/querydsl/querydsl/blob/master/querydsl-jpa/src/main/java/com/querydsl/jpa/impl/JPAQueryFactory.java#L17 ), it should be a runtime dependency and not only provided.
