qemux86*: change default wic wks to qemux86-directdisk
When runqemu is invoked with an image type (wic, hddimg etc) as a parameter,
the kernel value and command line parameters from qemuboot.conf
are ignored and not passed to qemu cmdline.
As an example, when using:
$ runqemu wic kvm
It results in no network interface and video mode warnings when qemu is up because
the -kernel and -append options were not passed.
Change qemu conf to use qemux86-directdisk.wks that supplies the kernel parameters
that are appended to the bootloader configuration when generating qemu wic
images instead of relying on qemuboot.conf.
