Correctly close the pipe used for scriptlet execution

We never had a call to pclose() in here before, leaving our file descriptor
in some sort of limbo state. In addition, clean up some of the other logic
such as directly calling exit(1) on a popen() failure rather than going to
our cleanup block, and handling and respecting the exit status of the
subprocess correctly.
