Title: [SPARK-3243] Don't use stale `spark-driver.*` system properties

If we set both `spark.driver.extraClassPath` and `--driver-class-path`, then the latter correctly overrides the former. However, the value of the system property `spark.driver.extraClassPath` still uses the former, which is actually not added to the class path. This may cause some confusion...

Of course, this also affects other options (i.e. java options, library path, memory...).
