[m-rev.] diff: make it possible run an installed compiler built in the C# grade

Make it possible to run an installed compiler built in the C# grade.

    Add a script script that runs an installed compiler built in the C#
    grade using Mono.  As with compilers built in the Java grade, the
    wrapper script we generate in the compiler directory only works
    in situ and we require a separate script for the installed version.

    XXX TODO: we will need to handle .NET differently, probably by simply
    renaming top_level.exe -> mercury_compile.exe.

     Install the new script if the compiler was built in the C# grade.
