don't change owner/perms/times through file:// symlinks
If we have files in partial/ from a previous invocation or similar such those could be symlinks created by file:// sources. The code is expecting only real files through and happily changes owner, modification times and permission on the file the symlink points to which tend to be files we have no business in touching in this way. Permissions of symlinks shouldn't be changed, changing owner is usually pointless to, but just to be sure we pick the easy way out and use lchown, check for symlinks before chmod/utimes.
