bpf, selftests: Adjust few selftest result_unpriv outcomes

Browse source 
commit 1bad6fd52be4ce12d207e2820ceb0f29ab31fc53 upstream.

Given we don't need to simulate the speculative domain for registers with
immediates anymore since the verifier uses direct imm-based rewrites instead
of having to mask, we can also lift a few cases that were previously rejected.
