qemux86: drop resolution setting via uvesafb

Browse Source 
I am not sure if this has ever worked, but uvesafb is a really
outdated (VBE from the 1990s), awkward (needs v86d) and limited
(no support for high resolutions) way to do it.

The specific reason 640x480-32 was introduced (ages ago) was
to force 32 bit mode with vmware driver, as 16bit had rendering issues.

The modern, supported option is video=... kernel parameter documented here:
https://wiki.archlinux.org/index.php/kernel_mode_setting#Forcing_modes_and_EDID
https://github.com/torvalds/linux/blob/master/Documentation/fb/modedb.rst
which can be passed directly to runqemu and doesn't require special
kernel modules.

Sato under X will continue to use 640x480 as that is hardcoded into
xorg.conf under qemu.
