[PATCH v3] build: install notmuch-emacs-mua.desktop file with emacs

[Jani Nikula]

There is really no need to have a separate install target for the
desktop file. Just install the desktop file with emacs, with a
configure option to opt out.

---

v3: check for desktop-file-install in configure.

I don't see a reason to differentiate between "with desktop" and "have
desktop-file-install", so I'm simply setting WITH_DESKTOP=0 if
desktop-file-install is not available.
