Thanks for this!
You don't use it, but that's ok, I'll add that policy handling myself after
merging. I have some notes about documentation / setup for both commits.

It would be nice to mention CONFIG_IMA_READ_POLICY=y in
testcases/kernel/security/integrity/ima/README.md as it's required.
That trivial thing I could do myself, but it'd help to add more info for setup
needed (and it's always preferred to do the setup, if possible, but for some
tests e.g. EVM testing in evm_overlay.sh it must be during the installation).

nit: actually sed was meant to be added in this commit (I reported in previous
one).

Kind regards,
