Sign kernel-modules by the keys created by kernel ( aligned with
the centos stx behaviour).
Put the keys into linux(-rt)-kbuild-5.10 package and they will be used
to sign the out of tree kernel modules.
Change the private key's name in kernel-modules according to kernel.
Enable oot kernel-modules' signing by default.
Test Plan:
- PASS: Build kernel-std/kernel-rt.
- PASS: Build the 7 oot kernel modules for both kernel-std/kernel-rt.
- PASS: Build the iso for kernel-std and boot up and probe ko for
every oot kernel-moudles without warning.
- PASS: Build the test iso for kernel-rt and boot up and probe ko for
every oot kernel-moudles without warning.
