Use wprefs_bindir output variable to set WPrefs path in menus.

The path to WPrefs has been hardcoded in many of the menu files to
/usr/local/GNUstep/Applications/WPrefs.app/WPrefs, which would only actually
work if the user ran something like:
     ./configure --with-gnustepdir=/usr/local/GNUstep
during build.

Instead, we add a .in extension to all menu files with this issue and use sed
to use the actual WPrefs path (given by the wprefs_bindir output variable) and
generate a new menu file.

A very similar idea is already used to generate the WMState file, which sets
WPrefs as the command for the Window Maker logo tile in the dock.
