[m-rev.] for review: shell script for C# grade uses absolute path

[Sebastian Godelet]

For review by anyone.

The generated shell script to launch C# executables does not use
absolute pathes, this patch fixes that (now works the same as the Java
grade).

compiler/compile_target_code.m:
    Assigning script directory to DIR and use that to launch the CLI
interpreter.

Sebastian.
