fix permission denied

[tjingrant]

Perform chmod +x to codegen_test.sh.in, otherwise we have:

Start 6: codegen_test
Process not started
 /home/.../isl/codegen_test.sh
[permission denied]
6/6 Test #6: codegen_test .....................***Not Run   0.00 sec

Thank you. Is setting the executable bit for codegen_test.sh.i sufficient? At the end, it's the file generated from it will be executed.

I can quote Brad King on this thread (https://itk.org/Bug/bug_relationship_graph.php?bug_id=10126&graph=relation):

The configure_file() command copies/edits a file from some source to a destination. It copies the permissions from the source location.

Also, it works in our environment (RHEL + PowerPC).

Thanks!
