Change to Readdirnames for some cases

Browse Source 
There was a couple uses of Readdir/ReadDir here where the only thing the return
value was used for was the Name of the entry. This is exactly what Readdirnames
returns, so we can avoid the overhead of making/returning a bunch of interfaces
and calling lstat everytime in the case of Readdir(-1).
