Add ctest timeout to prevent MooreScripts.hlt1stopstart test to hang forever

When MooreScripts.hlt1stopstart takes more than 10min, the QMTest wrapper tries to kill the process, but it then hangs forever waiting for something to happen before exiting an give control back to ctest.

I do not know what is special with ARM machines, but I saw it happening there. For example, I spot it by chance in lhcb-2025-patches-mr/102, where I killed the stale job to finally see ctest reporting a running time of 12700s (~3.5 hours).

This MR instructs ctest not to let the QMTest wrapper of MooreScripts.hlt1stopstart wait forever.
