Add guile-config

[Alex Sassmannshausen]

Hello,

Attached you should find a working patch for guile-config, a library for
Guile that should make maintaining command-line options and
configuration files for your scripts/programs easier.

I'm preparing a 0.1 Release announcement for this project too.

I ran it through `guix lint` and it seemed to be fine, but let me know
if you have any comments!

Best wishes,
Alex
