fix empty glob() error (#98)

tl;dr : the issue description and repro:
https://github.com/gdevillele/debug_bazel

I am trying to build native C libs for Android using Bazel and
`rules_android_ndk`, and am getting the following error:

```
glob pattern 'lib64/**/*' didn't match anything, but allow_empty is set to False
```

This is due to a breaking change introduced in Bazel 8.0.
(bazelbuild/bazel#8195)

Note: I am still a beginner with Bazel, so let me know if this is not
the correct way of fixing this.
Thank you 🙂

Fix github release flow (#78)

* Properly set release test command
* Correctly generate WORKSPACE stub in release_prep.sh
* Adjust example WORKSPACE stub to make example WORKSPACE generation
more straightforward.
* Make release_prep.sh executable

Github workflow-based releases working properly in my fork:
https://github.com/ted-xie/rules_android_ndk/releases/tag/v0.1.7

Ignore ci.yaml and buildifier.yaml from rules-template (#77)

More NDK libs: add native_app_glue cc_library and example for android…

…/log.h (#73)

Should help with #55.
