Currently, run.go's *dir tests allow "x.go" to be imported interchangeably as either "x" or "./x". This is generally fine, but can cause problems when "x" is the name of a standard library package (e.g., "fixedbugs/bug345.dir/io.go"). This CL is an automated rewrite to change all `import "x"` directives to use `import "./x"` instead. It has no effect today, but will allow subsequent CLs to update test/run.go to resolve "./x" to "test/x" to avoid stdlib collisions.
