selftests/bpf: Add additional tests for bpf_lookup_*_key()
Add a test to ensure that bpf_lookup_user_key() creates a referenced special keyring when the KEY_LOOKUP_CREATE flag is passed to this function. Ensure that the kfunc rejects invalid flags. Ensure that a keyring can be obtained from bpf_lookup_system_key() when one of the pre-determined keyring IDs is provided. The test is currently blacklisted for s390x (JIT does not support calling kernel function).
