selftests: ipc: change operation not supported error number

Browse Source 
The application doesn't know what ENOTSUPP means, as it is a kernelspace
error code and the application doesn't have access to kernelspace error
codes.I used EOPNOTSUPP in its place as that is an error number the
application will recognize and know an operation is being attempted that
it cannot support.
