[bug#65097] [PATCH] gnu: Add tk-img.

[cage]

Hi!

With this patch I tried to address all the issues that was pointed out
(hope they are fine :)) except one:

> One last thing, the source of tk-img carries many 'contrib' sources;
> they should be removed in a snippet to ensure only Guix-provided system
> libraries are used instead.

Because I was not able to find out the contribs sources.

Also, for the record, the problem with  tests is not that the Tk (as I
erroneously thought)  executable can not  be found but that,  for some
reasons, the tcl script seems to fails to resolve Tk as dependency:

$ tclsh

% package require Tk → raise an error

the same line works on my other system (Debian)

Bye!
C.
