We could run D-Bus from a login shell.  The reason I didn’t opt for this
is that GDM launches D-Bus from a stripped-down environment.  It’s not
clear to me if there’s a reason for doing so, or if it was just the way
the code came together.  Essentially, I’m trying to be conservative.

I’m still holding out hope that a future “user sessions” feature in Guix
will make all of these hacks go away.  :)

I pushed a nicer version (following the style of the “xinitrc” code)
with a long comment as dcb3a0fe0a086b4762a721e9b1da64826d5160d0.

Thanks for the review!
