[PATCH 1/2] kselftest/arm64: Don't leak pipe fds in pac.exec_sign_all()

[Mark Brown]

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.
