The first argument of the executable was used to get its path, but it is
not reliable because the executer can specify any arbitrary string. Use the
interfaces provided by QEMU and the platform to get those paths.

This change also changes the icon shown in the "about" window to QEMU's
cute one.

Looks good to me, but I'd like to have an additional macos review for
this one.

thanks,
