Nobody says that it was mounted on the host.

When a recent kernel boots in EFI mode, it always creates the directory
/sys/firmware/efi/efivars/, regardless whether support for efivarfs was
configured in the kernel (see drivers/firmware/efi/efi.c).

That means that we might have the directory and the mount will still
always fail. Anyway, failing to mount efivarfs should not prevent you
from using arch-chroot, as it only prevents you from manipulating efi
variables, but not from performing other important tasks.
