Fix for bug 32220 (checksetup.pl gives bad permissions). Majority of

patch submitted by seth@cs.brandeis.edu (Seth Landsman).  checksetup.pl
now no longer twiddles the permissions of the contrib folder, and
properly sets the permissions on the folders inside the data folder.

+# for slightly neater code and lets us do things like determine exactly which
+# files are executable and which ones are not.

+# Not all directories have permissions changed on them.  i.e., changing ./CVS
