fs: add a temporary fix for re-evaluation support

Browse Source 
This is needed to give users a grace period before actually breaking
modules that re-evaluate fs sources from context where internal modules
are not allowed, e.g. older version of graceful-fs module.

To be reverted in Node.js 7.0

Fixes: #5097, see also #1898, #2026, and #4525.
