MINOR: reload4j build dependency fixes (#12144)

* Replace `log4j` with `reload4j` in `copyDependantLibs`. Since we have
  some projects that have an explicit `reload4j` dependency, it
  was included in the final release release tar - i.e. it was effectively
  a workaround for this bug.
* Exclude `log4j` and `slf4j-log4j12` transitive dependencies for
  `streams:upgrade-system-tests`. Versions 0100 and 0101
  had a transitive dependency to `log4j` and `slf4j-log4j12` via
  `zkclient` and `zookeeper`. This avoids classpath conflicts that lead
  to [NoSuchFieldError](https://github.com/qos-ch/reload4j/issues/41) in
  system tests.
