scmutil: don't try to delete origbackup symlinks to directories (issue5731)

When origbackuppath is set, when looking to see if a file we are backing up
conflicts with a directory in the origbackuppath, we incorrectly match on
symlinks to directories.  This means we try to call vfs.rmtree on the
symlink, which fails.
