[ Upstream commit 27141b690547da5650a420f26ec369ba142a9ebb ]

The PAC exec_sign_all() test spawns some child processes, creating pipes to be stdin and stdout for the child. It cleans up most of the file descriptors that are created as part of this but neglects to clean up the parent end of the child stdin and stdout. Add the missing close() calls.
