x86/openeuler_config: disable CONFIG_EFI_VARS

hulk inclusion
category: config
bugzilla: 31390
CVE: NA

Accessing sysfs-efivars interface '/sys/firmware/efi/vars' may have some
problem. We can access the new efivarfs interface
'/sys/firmware/efi/efivars' instead. So disable CONFIG_EFI_VARS and keep
CONFIG_EFIVAR_FS enabled.
