[roll] Roll infra/recipes [tree_closer] Support closing based on percent of builders

The number of builders watched by the tree-closer has increased from 77
to 169 in the last 5 years, but the tree-closer was still closing the
tree when only 5 builders were failing, which had become much more often
with more builders due to baseline flakiness levels, leading to false
positive tree closures.

By making the closure conditional on a percentage instead of a hardcoded
number of builders, we can ensure the tree-closer doesn't close the tree
more often solely due to the console gaining more builders.
