RSDK-8096 fix module-in-process with tarball

[abe-winter]

What changed

• make JAR_PATH an abs path in the module-in-process intent

Why

Startup hangs without this.

Testing

For now, manual tests:

Before

logcat would show:

W  ClassLoader referenced unknown path: ./module.jar
E  error running thread for com.viam.sdk.android.examples.module.MyModuleInProcess
  java.lang.ClassNotFoundException: com.viam.sdk.android.module.fake.FakeContext

and RDK logs showed Waiting for module to complete startup and registration forever:
