qt5base-lts/tests/auto/network/kernel/qdnslookup/tst_qdnslookup.cpp
Marc Mutz b1afa3bed4 Stabilize QDnsLookup test 
Use 15s instead of 10 (one check took 7.5s on my development machine, even).

Port to QTR_VERIFY_WITH_TIMEOUT instead of rolling our own waitForDone(),
as that reports (within limits) by how much the timeout was exceeded.
