video/logo: don't select LOGO_LINUX_MONO and LOGO_LINUX_VGA16 by default

Nowadays, nearly all systems have a color depth of eight or more and
are thus able to display the clut224 logo. This means that the
monochrome and vga16 logos will never be displayed on an average
machine and are thus just a waste of bytes.

Set CONFIG_LOGO_LINUX_MONO and CONFIG_LOGO_LINUX_VGA16 configuration
symbols to no by default.
