Use remap_paths to android_tools

This ensures that the `all_android_tools_deploy.jar` and `ImportDepsChecker_deploy.jar` artifacts end up in the root of the `tar` where `exports_files` is able to reference them.

Before this PR the tar had the following directory structure:
```
  ./
  ./BUILD
  ./WORKSPACE
  ./desugar_jdk_libs.jar
  ./version.txt
  ./src/java_tools/import_deps_checker/java/com/google/devtools/build/importdeps/ImportDepsChecker_deploy.jar
  ./src/tools/android/java/com/google/devtools/build/android/all_android_tools_deploy.jar
```

After:
```
  BUILD
  ImportDepsChecker_deploy.jar
  WORKSPACE
  all_android_tools_deploy.jar
  desugar_jdk_libs.jar
  version.txt
```

Closes bazelbuild#17187.
