Set to critical since blocker for master

It seems that the issue appeared in 80% of build ISO job, but the rest 20% passed successfully

Seems like the issue is caused by the recent commit to fuel-library https://github.com/openstack/fuel-library/commit/de7a5778ae13939150461048e10a4012f64893a1

    Declare RANDFILE to avoid issues with unable to write it

    Remove error "unable to write 'random state'", cause by default
    there is no explicit home to set it and remove 'PRNG not seeded'
    by setting RANDFILE to do it.

    Also lower dhparam size to avoid 'execution expired' errors.
