Enhance the ext_skel.php script file

- File is now executable
- Shebang added on top
- Normal UTF-8 encoding instead of UTF-8 with BOM
- trailing whitespaces trimmed as a CS fix
- Closing PHP tag removed in favor of readability, avoiding possible
  issues with whitespaces, and to comply with current CS from the
  PHP ecosystem - PSRs etc.
