Cyrill Gorcunov 55290abcfc kvm tools: Fix VESA BIOS mode info ...

Some VGA data such as VESA info needs a proper tuning for addresses
passed on kernel requests.  We returned linear addresses there while
spec points out that far pointers are needed.

This fixes a long-standing issue that caused Linux kernel to never exit
the mode scanning loop in arch/x86/boot/video-vesa.c::vesa_probe()
because returned mode info table segment/offset pair was bogus. The
issue triggered on some machines when CONFIG_FB_VESA was disabled.

Also use already VESA structures defined in <boot/vesa.h> header now
that we no longer use the struct to store VESA BIOS data.
