installer: Load uvesafb kernel module.
Fixes <https://bugs.gnu.org/40538>. Machines without Kernel Mode Setting (those with many old and current AMD GPUs, SiS GPUs, …) need uvesafb to show the GUI installer. Some may also need a kernel parameter like nomodeset or vga=793, but we leave that for the user to specify in GRUB. * gnu/system/install.scm (uvesafb-shepherd-service): New procedure. (uvesafb-service-type): New variable. (%installation-services): Add it. Co-authored-by: Ludovic Courtès <ludo@gnu.org>
