Rmdir checked that the directory existed with GetMetadata and then
checked it was empty with ListFolder, but ListFolder already reports a
missing path and a path that is a file, so the first request was
redundant.
Drop the GetMetadata call and map the ListFolder lookup errors onto the
same sentinel errors as before, so a missing directory still returns
fs.ErrorDirNotFound and a file still returns fs.ErrorIsFile. Limit is
set to 1 as only the presence of an entry matters, and HasMore is
checked as well so a full first page is not read as an empty directory.
