Seems to work, so I've pushed it to git. In the next upload, we'll
have:

    dbus-user-session (Architecture: linux-any) Provides: d-d-s-b
    dbus-x11 (Architecture: any) Provides: d-d-s-b [!linux-any]

so every architecture will have exactly one d-d-s-b implementation.

Build-time tests are still responsible for starting a dbus-daemon
if they need one: the API guarantee of the dbus-session-bus virtual
package is only for "normal" GUI logins (deliberately left a bit vague
so that dbus-x11 can be an implementation of it), and buildds are not
one of those. The preferred interfaces for this are to use the
dbus-run-session "adverb":

    dbus-run-session -- make check

or invoke dbus-daemon directly if more control is needed:
