shuilt: re-introduce speedup The previous fix for read_tree_values fixed the issue with sh not supporting arrays, but looping over paths and counting them. Hover each count increment requires spawning a subshell. For a large number of paths, this can eat away any performance benefits of using read_tree_values. Since we only care whether the count is greater than one, detect that and break out of the loop early to re-introduce the performance improvement.
