chromium-extension: Compute json at argument evaluation time.

Browse source 
* gnu/build/chromium-extension.scm (make-chromium-extension): Make use of the
make-signing-key procedure inside the argument field, making sure that it is
not evaluated at file-load time.  This would otherwise try to resolve gnutls
when we can't guarantee it's defined because of dependency cycles.
