[bug#67793] Add exprtk package to Guix

[Steve George]

Hi Lars,

I came across your patch and took a quick look. You seem to only install
the exprtk.hpp file, but the Github repository has lots of other things. 
Is this what you intended?

[Lars Bilke]

Dear Futurile,

yes, copying exprtk.hpp only is intended. It contains the full (header-only) library. The license file is also copied into the store package.

Sincerely,
Lars
