On windows, executing dfscleanup -B incorrectly lists files as "not in cluster", and the -D swith will also remove them.

It seems that dfscleanup script does not convert slashes when checking filenames, which in this case (windows) is needed.

Steps to reproduce

• clear all caches
• navigate site, log in w. different users
• cache-block files, user-info cache files and ezjscore packed cached files are stored on dfs share
• run dfscleanup -B: these files are listed as "not in cluster"
• run dfscleanup -B -D: these files get deleted
• go to site again: everything is broken
• clear all caches: all is fine
