HADOOP-19072. S3A: expand optimisations on stores with "fs.s3a.performance.flags" for mkdir (#6543)
If the flag list in fs.s3a.performance.flags includes "mkdir"
then the safety check of a walk up the tree to look for a parent directory,
-done to verify a directory isn't being created under a file- are skipped.

This saves the cost of multiple list operations.
