Bug description:
This work is authorized by an approved UOS spec and blueprint at
https://wiki.ubuntu.com/Spec/InstallingUnsignedSecureBoot
Add code to implement secure boot checks. Unsigned or incorrectly
signed modules will continue to install while tainting the kernel
_until_ EFI_SECURE_BOOT_SIG_ENFORCE is enabled.
When EFI_SECURE_BOOT_SIG_ENFORCE is enabled, then the only recourse
for platforms booting in secure boot mode with a DKMS dependency is to
disable secure boot using mokutil:
sudo mokutil --disable-validation
sudo reboot
