Don't add duplicates to javaclasspath when run in home directory (bug #45683).

* ov-java.cc (initial_class_path): Get current working directory (cwd) and home
directory (home_dir).  Don't read in javaclasspath.txt from home directory or
java install directory if either of these is the same as cwd.
