archivers/lzip: Update to 1.22

This includes the following changes:

• Report an error if a file name is empty.
• Make '-o' behave like '-c', but writing to file instead of stdout.
• Do not open output if input is a terminal.
• Replace 'decompressed', 'compressed' with 'out', 'in' in output.
• Several fixes and improvements, improved test coverage.

On the way switch from PORTVERSION to DISTVERSION and add a LICENSE_FILE
(while the license itselfs does not change from GPLv2).
