I am not quite sure the purpose of this MR. The config option is already
turned on in RHEL and in Fedora, though in different places.
```
cat redhat/configs/ark/generic/x86/CONFIG_EFI_SECRET
CONFIG_EFI_SECRET=m
cat redhat/configs/fedora/generic/CONFIG_EFI_SECRET
CONFIG_EFI_SECRET=m
```
This MR is not a clean-up as it does not delete either of these entries. It
does not change the RHEL config in practice, because the option depends on
X86_64 at this point.
