configs: Use proper keywordargs for RedirectPath in apu_se
configs: Use proper keywordargs for RedirectPath in apu_se

RedirectPath uses app_path and host_paths instead of src and dests.
This patch fixes that in apu_se.

The patch also changes the formatting for those lines, as simply
replacing dests with host_paths put the lines over the 80 char limit.
