feedback about config file name on MacOS

Browse Source 
When hunting for player's run-time config file under MacOS/OSX,
nethack looks for .nethackrc (or $HOME/.nethackrc), then if not
found it looks for
 "$HOME/Library/Preferences/NetHack Defaults", and finally for
 "$HOME/Library/Preferences/NetHack Defaults.txt".
When none of those exists, the last choice has been being left in
configfile[] and can get used in messages.

The menu for entering the tutorial includes a tip about setting
OPTIONS=!tutorial in the config file, but it was showing the third
choice rather than the first when none of them are found.  Change
config file name setup to remember the first name rather than the
last when it represents a non-existant/not-yet-existent file, so
that the tip recommnends the standard Unix name rather than the
Mac-specific one.
