gnu: icedove-minimal: Add argument to desktop file.

Icedove was not able to handle mailto: links, even if it responded to
them, it only activated the window, but didn't compose a new email.
Calling it directly by `icedove mailto:...` worked. According to:
<https://lists.debian.org/debian-user/2015/06/msg01071.html>
It was missing the argument in the `Exec` line of the desktop file.

* gnu/packages/gnuzilla.scm (icedove-minimal)[phases]
  {install-desktop-file}: Add arguments to Exe line in .desktop file.
