When clearing the astroid cache, some tests fails due to
cache inconsistencies, where some objects had a different
builtins object referenced.
This saves the builtins module and makes sure to add it
back to the astroid_cache after the tests finishes.
The builtins module is special, since some of the
transforms for a couple of its objects (str, bytes etc)
are executed only once, so astroid_bootstrapping will be
useless for retrieving the original builtins module.
