selftests: bpf: Skip write only files in debugfs
DebugFS for netdevsim now contains some "action trigger" files
which are write only. Don't try to capture the contents of those.
Note that we can't use os.access() because the script requires
root.
Fixes: 4418f862d675 ("netdevsim: implement support for devlink region and snapshots")
