ltp_clone_quick is still part of the old API and only uses clone2. I
think it should be replaced with tst_clone. This may require extending
tst_clone. In fact we probably need a test variant to switch between the
clone2 and clone3 syscalls when using tst_clone.

I'll leave it to you whether you want to try that and rebase this patch
set on it.
