nvidia-kernel-{source,dkms} don't use upstream's conftest.sh to test for
availability of features, instead we ship (probably for historic reasons
where conftest.sh was not working properly) a manually generated
conftest.h that says

/* Implement conftest.sh function efi_enabled */

Anyway, checks for efi.h and efi_enabled were only introduced in 310.14
and have not been backported to the 304.xx series by Nvidia so far. So
this only affects the Nvidia driver in experimental.
