4.9.3 AppImage issue

[Paul Buxton]

So to summarise.
Your machine-id is in /var/lib/dbus
Our dbus library is looking in /usr/local/var/lib/dbus, and also /etc

Just checking my local machine (Windows with WSL running Ubuntu 18,
not exactly representative), and I appear to have /etc/machine-id,and
/var/lib/dbus/machine-id but not /usr/local/lib/dbus.
I can check a more realistic machine tomorrow.
But looking at the Appimage build, we build dbus from source, and
looking at the dbus project code, it looks like the path that is
searched is a build time option.
makefile.am:
..
DDBUS_MACHINE_UUID_FILE=\""$(localstatedir)/lib/dbus/machine-id"\
..

I am not 100% clear where localstatedir comes from, but I think
perhaps we want to change the configuration of the dbus build to
specify it to be /var instead of /usr/local/var

I will poke around some more when I get some time.
