update fuel_syntax_checks.sh to leverage the fuel-library rake syntax task

[Alex Schultz]

As part of our integration into openstack-infra CI, we created a syntax task via a Rakefile in fuel-library. The previous Fuel CI implementation of lint and syntax checks were reimplemented as standard rake tasks. We are running the same lint/syntax jobs as openstack-infra CI jobs so we should either remove the fuellib_review_syntax_check job or update the script we currently leverage to use the same method as the openstack-infra jobs.

Would be nice to have this to the 8.0 as well (non release anyway, but improves CI a lot)

Remove fuellib review_syntax_check and unit_tests jobs

Jobs fuellib_review_syntax_check and fuellib_unit_tests
should be removed from stable/8.0 and master because we
already have the same functionality in the upstream
OpenStack jobs.
