Fix dependency information for RULES

A SpecInfo (inside IdInfo) keeps track of the free variables of a RULE
so that the occurrency analyser knows about its dependencies.

Previously it was only tracking the *rhs* free vars, but it should
really include the *lhs* ones too.  See Note [Rule dependency info]
in IdInfo.

This fixes a WARNING when compiling some libraries.
