Remove setup_el_dirs dependency in pe_sles task

Previously the sles rake task depended on setup_el_dirs as defined in
mock.rake. This commit makes a similar fix to the mock fix, by making
directories immediately before copying/linking into them so that the pathing is
known and directories can be created.
