Our attempt to evenly distribute tests across shards struggles a bit
because certain long-running targets are very difficult to distinguish
in ResultDB, namely racebench and the test directory tests. These are
the only tests where the JSON output from dist omits the variant from
the package, making it impossible to distinguish them in the test result
data. My current suspicion is that this is preventing the load balancing
from being effective for the race builders in particular, though I worry
the longtest builders have a similar situation with the test directory
tests.
For #65814.
