tools: fix inspector-check reporting

Currently the inspector-check rule does not store the node when the
usage of a require('inspector') is done. This means that it is not
possible to disable this rule. For example, if you add the following to
a test that uses the inspector module:
//common.skipIfInspectorDisabled();
/* eslint-disable inspector-check */

This will not disable the check and there will still be a lint error
reported.

This commit stores the node where the require statement is done which
allows for the rule to also be disabled.
