Paul Chaignon 7ec899ac90 selftests/bpf: Negative test case for ref_obj_id in args
This patch adds a test case, as shown below, for the verifier error
"more than one arg with ref_obj_id".

    0: (b7) r2 = 20
    1: (b7) r3 = 0
    2: (18) r1 = 0xffff92cee3cbc600
    4: (85) call bpf_ringbuf_reserve#131
    5: (55) if r0 == 0x0 goto pc+3
    6: (bf) r1 = r0
    7: (bf) r2 = r0
    8: (85) call bpf_tcp_raw_gen_syncookie_ipv4#204
    9: (95) exit

This error is currently incorrectly reported as a verifier bug, with a
warning. The next patch in this series will address that.
