gen_fvp_tftf_yaml.sh: Increase monitor/interactive timeout to 7min

We have jobs (e.g. fvp-tspd,fvp-extensive:fvp-tftf-fip.tftf-aemv8a-tspd)
which run 5min on average, and 95+% of that time is spent in single
interactive "test". Thus, on any disturbance, such jobs start to timeout
(28% of the last 25 jobs at the time of writing). So, increase the
timeout to 7min.
