[bug#41256] [PATCH] gnu: icedove: Add a desktop file.

[Jonathan Brielmaier]

Thunderbird upstream doesn't provide any desktop file. So we have
to create it downstream. I filed an upstream bug:
https://bugzilla.mozilla.org/show_bug.cgi?id=1637575

* gnu/packages/gnuzilla.scm (icedove)[phases]: Add install-desktop-file phase.
