src/klish-plugin-infix: fixes to 'dir' and 'show log' commands

These changes are designed to make the experience working with log files
easier.  Both listing available log files and viewing them.

 - replace C dir@infix with a shell script for easier extensions,
   e.g., we want to show both available .cfg and log files
 - add support for gunzipping .gz log files before viewing them
