Ensure efivars are mounted before installing a UEFI bootloader (mga#31008)
The old way of accessing EFI NVRAM variables via /sys/firmware/efi/vars
was removed in Linux 6.0. The new way is to use the efivarfs pseudo-
filesystem, which is usually mounted at /sys/firmware/efi/efivars. We
need to make sure this is actually mounted before attempting to install
a UEFI bootloader, otherwise any attempt to write to the EFI NVRAM will
fail.
