Switch flutter_build_apk_health_tests to use a subset of current tests. (#159004)

Towards https://github.com/flutter/flutter/issues/159000 as part of
debugging issues such as
https://github.com/flutter/flutter/issues/158560.

On a `bringup: true` shard, run a number of `flutter build apk` tests in
succession to try and routinely trigger timeouts and crashes, so we can
test other hypotheses on how to fix this problem (i.e. potentially
around increasing memory, changing daemon configuration, aggressively
killing processes, etc).
