Allow for specifying the output_dir
Allow for passing the output_dir in the process-templates scripts so that it doesn't overwrites the templates in the src dir. This is a desired feature when running the script from a t-h-t installed system-wide. Change-Id: I47994d34f47a4084a11124bc9075cb2f457889ea
