cmd: policies: test: Fix policyTouchesPathPredicate

pathexp.Equals() was wrong. This version is at least more right if it
isn't completely.

We check for Contains both ways because either the specified or policy
paths may have globs, and we want to include policies whose path is more
general (contains) the specified path.

For example, given the input path "/o/p/*/s/u/i", we want to include
policies with the path "/o/p/e/s/u/i". But, given the input path
"/o/p/e/s/u/i", we also want to include policies with paths
"/o/p/*/s/u/i" since the former does resolve to the latter.
