bpf: Add bpf_jit_supports_fsession()
The added fsession does not prevent running on those architectures, that
haven't added fsession support.
For example, try to run fsession tests on arm64:
test_fsession_basic:PASS:fsession_test__open_and_load 0 nsec
test_fsession_basic:PASS:fsession_attach 0 nsec
check_result:FAIL:test_run_opts err unexpected error: -14 (errno 14)
In order to prevent such errors, add bpf_jit_supports_fsession() to guard
those architectures.
Fixes: 2d419c44658f ("bpf: add fsession support")
