Jeff Squyres 9f21ea437c java: clean up MPI Java configury
The Java configury is split into two parts:

1. Determine if we want MPI Java bindings.
2. Find the Java compiler (and related).

This commit does a few things:

- Move the "Find the Java compiler" step from OPAL to OMPI (because
  there is no Java in OPAL, and there doesn't appear to be any
  immanent danger that there will be).
  - As a direct consequence, remove the --enable-java CLI option
    (--enable-mpi-java still remains).  Enabling the MPI Java bindings
    and enabling Java are now considered the same thing (since there
    is no Java elsewhere in the code base, the different was
    meaningless).
- Only invoke the "Find the Java compiler" step if we actually want
  the MPI Java bindings.
- A few miscellaneous Java-related cleanups in configury (E.g., change
  testing "$foo" == "1" to $foo -eq 1, etc.

This commit is mostly s/opal/ompi/gi in many places in configury and
shifting code around.  But it looks bigger than it actually is because
of two reasons:

1. Some files were renamed:
   * ompi_setup_java.m4 -> ompi_setup_mpi_java.m4 (setup MPI Java bindings)
   * opal_setup_java.m4 -> ompi_setup_java.m4 (setup Java compiler)
2. Indenting level changed in (the new) ompi_setup_java.m4.
