[FLINK-17963] [core] Revert execution environment patching in StatefulFunctionsJob

This is a revert of FLINK-16926, which was a temporary workaround for
the problem back in Flink 1.10.0 where values present in flink-conf.yaml
were not being respected via the StreamPlanEnvironment, which was used
when using a JobClusterEntrypoint to start the job.

This closes #118.
