Fix Bug 587: Use alternative storage location if platform's temp directory is mounted w/ noexec ; IOUtil API change!

Test whether executable files can be launched in temporary folder
by trying to run an empty executable file - if !( WINDOWS | OPENKODE )

TempDir:
1) ${java.io.tmpdir}/jogamp
2) $XDG_CACHE_HOME/jogamp - if !( ANDROID | MACOS | WINDOWS | OPENKODE )
3) $HOME/.jogamp

$XDG_CACHE_HOME defaults to $HOME/.cache

- TempFileCache: ${TempDir}/file_cache -> ${java.io.tmpdir}/jogamp/file_cache
- LauncherTempFileCache: ${TempDir}/file_cache -> ${java.io.tmpdir}/jogamp/file_cache
