[PATCH] tests: fix -nt test on low-resolution file systems

in w/45470 i re-arranged the C02 '-N cond' test to fix an issue i was seeing on
apfs. i didn't realise that in doing so i broke the -nt test that follows it on
low-res file systems like hfs+. (i still use it for ram disks, and i happened to
try building on one)

this should make it work everywhere
