[PATCH] KVM-test: Support qxl and vga parameters in make_qemu_command.

The behave is difference on RHEL6.0 and RHEL5.
On RHEL5, qxl and vag are two parameters. But on RHEL6, qxl
is one option in vga.
This patch could work on RHEL5 and RHEL6 hosts.
On RHEL6, if we set qxl and vga together in tests_base.cfg,
vga will be set to qxl, no matter what you set to vga.
