This is a followup to
https://dart-review.googlesource.com/c/sdk/+/386900.
Since manually sharding the co19 tests on the firefox configuration
by subdirectories there have been no infrastructure failures on the
ddc-linux-firefox bot.
This change reduces the number of shards per each subdirectory
shard as an experiment to see if this will cause one of them to start
causing failures.
