include symify.exe in the NetHack msdos package

Before using this updated packaging you will need
to do the following (one time):
    sh sys/msdos/fetch-cross-compiler.sh

And you'll need to update your Makefiles as follows.

On Linux:
    sh sys/msdos/setup.sh sys/unix/hints/linux.370

or on macOS;
    sh sys/msdos/setup.sh sys/unix/hints/macOS.370

Create the msdos package with:
    make CROSS_TO_MSDOS=1 package

sys/msdos/fetch-cross-compiler.sh
