selftests/bpf: fix timer/test_bad_ret subtest on test_progs-cpuv4 flavor
Because test_bad_ret main program is not written in assembly, we don't
control instruction indices in timer_cb_ret_bad() subprog. This bites us
in timer/test_bad_ret subtest, where we see difference between cpuv4 and
other flavors.
For now, make __msg() expectations not rely on instruction indices by
anchoring them around bpf_get_prandom_u32 call. Once we have regex/glob
support for __msg(), this can be expressed a bit more nicely, but for
now just mitigating the problem with available means.
