page: close stdout, reopen stdout/stderr for external viewer and removed useless RFNAMEG flag

Browse source 
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.
