Fixes the F1'97 Demo program (a racing game) not showing an icon in explorer.
This fixes a very special kind of icons which are embedded into the
executable by ancient Watcom C/C++ compilers.
Windows XP/2k3sp2 can show that icon.
Windows Vista/7 cannot show that icon.
Due to the different behavior of the various Windows versions, we
also added a testcase for our bots to protect that functionality in the future,
we committed that test by 0.4.15-dev-7076-g c00d41d91c (#6020)
