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

This is problematic using EFI to manage boot flow from Linux (E.g. via RAUC). https://www.kernel.org/doc/Documentation/filesystems/efivarfs.txt (From OE-Core rev: adc0a31169f59d0183c327347b9ab3bcebb1aef2) Signed-off-by: Haris Okanovic <haris.okanovic@ni.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org> Signed-off-by: Armin Kuster <akuster808@gmail.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
