tf-daily: move trigger time from early to late day

An 'early' trigger degrades CI build-test latency for people working
in Asia (Shanghai), so move the trigger time late day to lessen
the impact for this region.

With this change, the two TF daily triggers, tf-daily and tf-m-nightly
for TF-A and TF-M respectively, would trigger with a difference of 2
hours, tf-daily triggering first:

Job           Cron time
------------  ---------
tf-daily      H 19 * * *
tf-m-nightly  H 21 * * *

tf-daily single run takes about 2 hrs for completion [1], but some
builds may take longer, approx. 4hrs, so for some days, both daily
trigger will be running in parallel for some period of time.
