This function is now only used in one place, to print the version of
qemu in direct mode, when debugging is enabled.
Remove this function and replace with a direct command invocation
('qemu --version'). We only need to run this command when debugging
is enabled, and we copy all of the output to the debug channel.
I have made the assumption here that qemu -version does not try to
create a display device. (The previous invocation of qemu -help
actually ran 'qemu -display none -help' indicating that this was not
always the case.)
This is actually an improvement on before, since now we get to see the
full output of 'qemu --version'. The new output looks like:
libguestfs: begin testing qemu features
libguestfs: command: run: /usr/bin/qemu-kvm
libguestfs: command: run: \ -version
libguestfs: qemu: QEMU emulator version 10.1.0 (qemu-10.1.0-8.fc44)
