payloads/seabios: Enable SeaVGABIOS option if native text init supported 

SeaVGABIOS supports both the coreboot linear framebuffer and native EGA
text mode.  To use SeaBIOS interactively on standard VGA hardware a VBIOS
is needed; SeaVGABIOS is one such option.

TEST: Booted KFSN4-DRE with XGI Volari Z9s and SeaVGABIOS.  Was able to
interact with SeaBIOS and comboot menu, then booted Linux successfully.
VGA display was continuously usable from power on to Linux login.
