The test does the right thing if the path does not exist, so I'm not
sure if it is necessary.

support_can_ptrace would be misleading because even with YAMA scope
support, tracing direct subprocesses will still work.

I fact, I think we might be able to get this test to work even with
fairly restrictive YAMA scopes, by proper ordering of forks and using
execve to run tst-pldd.
