Ensure only the filtered environment variables are inherited from the OS

The recent change which modified inheritFromOS to use the intial
environment, rather than the current environment, introduced a bug such
that variables which had been cleaned from the environment where still set
in the data store.

This patch changes things such that a list of approved environment
variables is saved after the environment is cleaned and only the variables
in this list are inherited in inheritFromOS.
