31919: fix deadlock when a shell builtin with a multio redirection is used on the left side of a pipeline
Make sure stdin/out/err file descriptors are closed for the multio copy process, which means not re-using those descriptors after they are closed and marked FDT_UNUSED in fdtable[]. For completeness, initialize their fdtable[] state to FDT_EXTERNAL.
