module: preserve URL in the parent created by createRequire()

Previously, createRequire() does not preserve the URL it gets
passed in the mock parent module created, which can be
observable if it's used together with module.registerHooks().
This patch adds preservation of the URL if createRequire()
is invoked with one.
