gzip: Update to version 1.13

- Update from version 1.12 to 1.13
- Update of rootfile not required
- Changelog
    Noteworthy changes in release 1.13 (2023-08-19) [stable]
	Changes in behavior
	  zless now diagnoses gzip failures, if using less 623 or later.
	  When SIGPIPE is ignored, gzip now exits with status 2 (warning)
	   instead of status 1 (error) when writing to a broken pipe.  This is
	   more useful with programs like 'less' that treat gzip exit status 2
	   as a non-failure.
	Bug fixes
	  'gzip -d' no longer fails to report invalid compressed data
	   that uses a dictionary distance outside the input window.
	   [bug present since the beginning]
	  Port to C23, which does not allow K&R-style function definitions
	   with parameters, and which does not define __alignas_is_defined.
