gen_fvp_tftf_yaml.sh: lower TFTF jobs timeout values

Current tftf timeout values are too high for successful jobs (< 5
minutes, see [3] right-most column), and in case jobs are stuck due
intermittent issues [1], unnecessary time is spent. With lower times,
we can catch those intermittent jobs faster and retrigger these faster
as proposed by [2].
