fix W343-7 - strange topten output on Windows

Move the toptenwin option from flags to iflags to keep it out of
save files, thus preventing odd behavior from win32 (nethackW.exe) when
restoring and finishing games started and saved with tty (nethack.exe).
[See cvs log entry for flag.h for more complete explanation.]
