grub 2.12 introduced the `--is-supported` argument for fwsetup, and runs it for
efi systems to determine whether to show the uefi-firmware menu item.

The problem is that grub 2.06 does not support the `--is-supported` flag yet,
and calling it just crashes grub, causing the machine to reboot.

Showing a menu entry for uefi-firmware that may not work is infinitely better
than crashing and preventing the machine to boot, so remove the condition and
always show the menu entry.
