Launch file configuration for CPLEX is broken

Currently, the generated launch file for CPLEX solvers contains the subfolder `/lib` which is non-existent for CPLEX.

Example GIPSL config:
```
config {
solver := CPLEX [home:="/opt/ibm/ILOG/CPLEX_Studio221/cplex/bin/x86-64_linux", license:="bar"];
launchConfig := true [main := "org.emoflon.gips.gipsl.examples.mdvne.ExampleMdVNE"];
timeLimit := true [value := 10.0];
randomSeed := true [value := 0];
presolve := true;
debugOutput := true;
}
```

Generated run file:
```

```

The correct setting would be something like this:
```
[...]

[...]
```

**Another notice**: The license file path is irrelevant for GLPK + CPLEX -> We should make this optional in GIPSL. I'll open an issue for this, too.
