SystemTools: do not special case a junction in RemoveFile
The fix in !77 (merged) made the infastructure added by commit de83c4d4 unnecessary. Remove it.
Before this commit, when a file on Windows was deleted, it would check if a file is a junction and then delete just the junction.
Now just skip the special case of a junction and allow the rest of the code to delete it correctly. Can handle symlinks and junctions.
