make system bus optional

Don't require a system bus in SDL_dbus.c.
SDL uses only a session bus.

For example, if you are on WSL environment, you may have only activated a session bus.
Even on native Linux, you may be on such a system where dbus is not installed and you install it as a user (e.g. to $HOME).

What I did were (on Windows):

0. Install WSL, Ubuntu, and VcXsrv.
1. Run VcXsrv (without native opengl, fwiw).
2. Run "Bash on Ubuntu".
3. Type "export DISPLAY=:0.0" and press ENTER.
4. Type "dbus-run-session bash" and press ENTER.
5. Type "export XMODIFIERS=@im=fcitx" and press ENTER.
6. Type "fcitx -rd &" and press ENTER.
7. Run testime. (in SDL/test)

Without this patch, you cannot use fcitx in this case.
With this patch, you can.
