kernelsu: LSM: Identify modules by more than name

This is based on commit "LSM: Identify modules by more than name"
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=v6.8&id=f3b8788cde61b02f1e6c202f8fac4360e6adbafc

Which is a requirement to build on kernel 6.8+. I use 912 as the ID
for KernelSU as that's the date the Github repo was created.
