ci/anv: Temporarily halve TGL testing load

Browse source 
Our TGL machines are currently slightly oversubscribed (max. 17 jobs in
a pipeline on 15 DUTs). They're also currently suffering from
thermally-induced GPU throttling (being investigated), and a
thundering-herd network load effect: as all 15 jobs start at once, we
end up saturating one of our network links.

The combination of all three of these things means that TGL is often our
long pole in CI runs. Until we can ameliorate the two issues
constraining throughput (and a third where an unreliable hardware UART
sometimes kills jobs when it shouldn't), halve the workload so we at
least have some breathing room to absorb them.
