page: close stdout, reopen stdout/stderr for external viewer and removed useless RFNAMEG flag
we are not using stdout (fd=1) and it, so dup nullfd over it.
this drops the old window reference when using with -w flag.
the RFNAMEG flag isnt needed because we are calling newwindow()
which forks the namespace for us.
reopen stdin/stdout for the external viewer to the new window.
