initscripts/sysfs.sh: Mount /sys/firmware/efi/efivars when possible

Browse Source 
Without this change, efibootmgr is unable to recover BootOrder if lost
during a previous write operation, e.g. exceeded storage capacity. This
is problematic using EFI to manage boot flow from Linux (E.g. via RAUC).
