Bug 1219: IOUtil.testDirExe: Satisfactory when executed, more debug options

IOUtil.testDirExe():
  - Satisfactory when executed
    Failure to execute produce an IOException right at ProcessBuilder.start().
    Hence we can allow an unexpected process exit value,
    since we only want to learn whether executable files are allowed.

  - More debug options
    DEBUG_EXE:          'jogamp.debug.IOUtil.Exe'
    DEBUG_EXE_NOSTREAM: 'jogamp.debug.IOUtil.Exe.NoStream'

    - if DEBUG_EXE
      - a pre-existing 'jogamp_exe_tst'+<SUFFIX> will be used as-is.

      - the test-exe will not be deleted

      - StreamMonitor is being used to dump stdout/stderr
        if !DEBUG_EXE_NOSTREAM.
