#229 MinGW/MSYS2: Fix build of RC file and simplify code.

[Carlo Bramini]

Hello,
according to:
https://sourceforge.net/p/vice-emu/bugs/1227/
my compilation failed because emitted resource file used an unsupported path.
For fixing the problem and also simplify the code, I suggest to use a static resource file and add the path of the icon by just adding the "-I" option on the command line.
Attached patch fixes this issue and also the bug 1227.

Sincerely.
