[PATCH] gnu: Add dia.

[Roel Janssen]

Dear Guix,

Here's a patch for Dia.  I used a git commit because it doesn't seem
like there's going to be a new version soon, and this specific version
includes some bugfixes for building the program (which makes the package
recipe a lot simpler).

Subject: [PATCH] gnu: Add dia.

* gnu/packages/gnome.scm (dia): New variable.
