   ### What is this PR for?
   This PR reverts commit dd08a3966ef3b0b40f13d0291d7cac5ec3dd9f9c which was merged with #4715
   
   I have set the environment variable `ZEPPELIN_INTP_CLASSPATH_OVERRIDES`, which now no longer works due to the change.
   
   I have set the environment variable to the value `/usr/share/java/*`, which in my opinion represents a valid classpath.
   
   `printf %q "/usr/share/java/*"` results in `/usr/share/java/\*`, which is no longer a valid classpath.
