[v4l-utils PATCH-v2 2/4] dvbv5-zap.c: allow timeout with -x

[Jemma Denson <jdenson@gmail.com>]

Timeout handlers aren't set when running with -x (exit after tuning).
This patch adds handlers so -t can be used with -x.

Without a timeout dvbv5-zap will run forever if there's no signal,
preventing it's use by scripts to obtain signal stats.
