Use user home to integrate java for macOS

[rennsax]

Fix #213.

To integrate jdk at user home, set java_macos_integration_in_home = yes.

@rennsax Thanks for the effort!

A few points to consider:

• Add some documentation (to the README.md I'd guess)

  • similarly to the java_macos_integration_enable option

• Add tests (to the .github/workflows/tests.yml I'd guess)

  • This can ensure that a later feature / change does not break what You'd done

• I think You almost nailed the naming for the option:

  • starts with java_macos_integration_ - cool
  • however, I'd prefer if it was java_macos_integration_user_home

I hope the maintainer (@halcyon) should be able to help You with these, until then I'll try to test it locally, and give You feedback if I encounter some issues.

@mrmeszaros Thanks for your advices! I may struggle some time to deal with the tests.
