[Replicant] [libsamsung-ipc] [PATCH 4/4] tools: fix nv-data-md5 compilation with Replicant 6

When compiling nv-data-md5 under Replicant 6 we have:
    In function 'main':
    control reaches end of non-void function [-Werror=return-type]
    cc1: some warnings being treated as errors

So we simply need to add a return in the error path.

While we're at it, we use an exit code referenced in sysexits.h
to follow a standard. This can help differentiating between
different types of errors.

Thanks to that, it can also simplify the code when writing tests.
