[PATCH bpf-next 1/3] selftests/bpf: Remove sockmap update from bpf_iter_unix

[Michal Luczaj <mhal@rbox.co>]

BPF iterator programs that can update sockmaps will be limited to
iter/sockmap. Remove the update from the unix selftest.

This reverts commit 997b8483d44c ("selftests/bpf: Extend bpf_iter_unix to
attempt deadlocking").
