[Impact]
Kernel lockdown can be bypassed when UEFI secure boot is disabled or
unavailable and IMA appraisal is enabled.

[Backport]
Clean cherry-pick.

[Test]
Compile tested.

[Regression potential]
Low, but IMA appraisal could be affected as another check is added to the
ima_appraise_signature() function.
