Add Automatic-Module-Name manifest entry to Java jar files

**What language and solver does this apply to?**
Java

**Describe the problem you are trying to solve.**
The current Linux jar file cannot be used with the Java module system because it’s file name cannot be converted into an automatic module name. Adding this additional manifest entry will fix this.

**Describe the solution you'd like**
Add
`Automatic-Module-Name: com.google.ortools`
to the `ortools-java-xxx.jar` file

Add
`Automatic-Module-Name: com.google.ortools.linux`
to the `ortools-linux-xxx-xxxx.jar` file.

Similar automatic module names should be added to the other os specific jar files (i.e .windows, .mac)
