Don't assume that X11 autolaunch will work if DISPLAY is unset

In practice, it won't; other forms of autolaunch (like Mac OS launchd)
might, but we can't really assert either way.

I actually wonder whether to just disable test-autolaunch altogether, unless we can find something like Debian's xvfb-run (which runs a specified app under a temporary Xvfb server). It seems to me as though this test doesn't necessarily really test anything, and at worst it spuriously fails (in a minimal environment, with inaccessible X, etc.). It'd also be easy for it to leak a dbus-daemon/dbus-launch pair, which isn't ideal.

I'd like the Debian package build to be able to run the tests, one day...

Ops, need include "dbus/dbus-sysdeps.h" to fix build, introduced by calling _dbus_getenv().

When I wrote the patch, this file included dbus/dbus-sysdeps.h for _dbus_setenv, but I removed that in commit 412538b3b9. Reinstated and applied, 1.7.6.
