hw/s390x: Add the possibility to specify the netboot image on the command line
The file name of the netboot binary is currently hard-coded to
"s390-netboot.img", without a possibility for the user to select
an alternative firmware image here. That's unfortunate, especially
since the basics are already there: The filename is a property of
the s390-ipl device. So we just have to add a check whether the user
already provided the property and only set the default if the string
is still empty. Now it is possible to select a different firmware
image with "-global s390-ipl.netboot_fw=/path/to/s390-netboot.img".
