mkdir: warn when using mkdir on remotes which can't have empty directories

Browse Source 
It is a source of confusion for users that `rclone mkdir` on a remote
which can't have empty directories such as s3/b2 does nothing.

This emits a warning at NOTICE level if the user tries to mkdir a
directory not at the root for a remote which can't have empty
directories.
