UEFI (#5): grub-mkstandalone embedded config now insmod's all needed
modules (iso9660, search_label, normal, linux) and uses 'normal' to
load the full grub.cfg. Previous config couldn't find the ISO root.

ISOLINUX (#6, #7): Switch from menu.c32 to vesamenu.c32 for background
image support. Copies splash.png from branding. TIMEOUT 0 for instant
boot (no keyboard lag, no menu flicker). Dark theme with transparent
background over the splash image.

Also: added vesamenu.c32 and libcom32.c32 to build artifacts.
Removed console=ttyS0 from quiet boot (interferes with Plymouth).
Added splash to quiet boot kernel params.
