Usage without a session D-Bus instance

[WhyNotHugo]

I'm trying to use bluetuith on an embedded device (e.g.: a media centre; not a desktop system), but it fails to start. Apparently, bluetuith depends on the D-Bus session instance:

$ bluetuith
[!] Cannot start session DBus: exec: "dbus-launch": executable file not found in $PATH: executable file not found in $PATH

This particular error is because go-dbus tries to start a new dbus session instance if one is not running. This behaviour is never useful, since no other client can find this bus instance anyway.

This runtime dependency on a session D-Bus instance should be optional: it's required for connecting to pulseaudio/pipewire, but on systems without such services (or capabilities), setting up a D-Bus session instance on an embedded system with no persistent user home directories is a burden.

To be clear: the system D-Bus is obviously running as it is a dependency for bluez.

@WhyNotHugo I will look into this, however, the session DBus may be required for obexd (i.e. if you want to use OBEX services), but yes, it should be made optional.
