lang/emilua: Update to 0.6.0

ChangeLog: https://docs.emilua.org/api/0.6/changelog.html

 * Add FreeBSD’s jails support.
 * Add function format() to format strings. The implementation uses C++'s libfmt.
 * Convert decomposition functions from filesystem.path to properties:
   root_name, root_directory, root_path, relative_path, parent_path, filename,
   stem, extension.
 * Convert some filesystem.path properties to string: root_name, root_directory,
   filename, stem, extension.
 * filesystem.path.iterator() will return strings at each iteration now.
 * Add more functions to the module filesystem: exists(), is_block_file(),
   is_character_file(), is_directory(), is_fifo(), is_other(),
   is_regular_file(), is_socket(), is_symlink(), mode(). It was already possible
   to query for these attributes. These functions were added as an extra
   convenience.
 * Add yet more functions to the module filesystem: mkfifo(), mknod(),
   makedev().
 * New UNIX socket options to retrieve security labels and credentials from the
   remote process.
 * Remove HTTP & WebSocket classes. They should be offered as separate plugins.
 * file_descriptor implemented for Windows pipes and file.stream.
 * Many improvements to Windows version of system.spawn().
