analyze-timing.sh: check only last measurement occurrence

For some physical simulators, we have multiple SNR iterations.

The previous version of the script correctly retained only the last
measurement, but if a previous measurement condition set RC=1, the
script would fail although the final "good" run might fulfil the
measurement condition (IOW, it would show SUCCESS, but still fail on the
check).

Instead, check if all measurement lines finish on SUCCESS, which handles
the above case.
