selftests/bpf: Fix stack arg pruning test JOIN log expectation
Commit f414d20879ae ("bpf: Save DFS postorder numbers for program
instructions") changed bpf_compute_postorder() to use a real DFS, which
changes the postorder of this test's instructions and thus the insn edge
the arg track join at insn 10 is reported on:
arg JOIN insn 8 -> 10 r1: _ + fp0-8 => fp0-8|fp0+0
arg JOIN insn 8 -> 10 sa0: _ + fp0-8 => fp0-8|fp0+0
Update the r1 and sa0 expectations to the new output.
Fixes: f414d20879ae ("bpf: Save DFS postorder numbers for program instructions")
