Expand list of attributes inspected when collecting license information

## Expected Behavior
`LicensesInfo` / `LicenseInfo` will be collected by reviewing all attributes of objects passed in to the `gather_licenses_info` aspect.

## Actual Behavior
The list of attributes that are inspected for `LicenseInfo` / `LicensesInfo` does not gather licenses for all third party libraries included in an android app binary.

## Steps to Reproduce the Problem

1. Use `gather_licenses_info` aspect to collect license information for your `deps`

Note: the same way as shown in [this docstring](https://github.com/bazelbuild/rules_license/blob/main/rules/gather_licenses_info.bzl#L78)

## Specifications
- We found including `exports` allows us to find significantly more licenses when building an android binary.

- Version: 0.0.3
- Platform: Android

Start with rules/gather_licenses_info.bzl and the gather_licenses_info docstring linked in the issue. Review which attributes are inspected for LicenseInfo and LicensesInfo, include exports as specified, and verify that the aspect gathers licenses from more third-party libraries in an Android binary.
