chgserver: do not send system() back to client if stdio redirected (issue5992)
As the chg client doesn't know server-side stdio redirection, the server
shouldn't upcall on "runsystem" request if the stdio streams are redirected.
This patch teaches ui to remember the redirection flag, which is updated by
the caller right now. Future patches (for default) will add ui methods to
manage this flag internally.
