Add test for alpine and android apk formats

[terriko]

#1258 added support for both the android and the alpine formats which both use .apk extensions. It would be nice if we had a couple of very tiny files in each format to use with the tests, and tests to actually execute the code.

Not sure this is going to happen in time for the 3.0 release.

A bunch of the tests now use Alpine apks so these are well covered. I don't see any with android .apk files yet, so we could still use a small test added to https://github.com/intel/cve-bin-tool/tree/main/test/assets for this purpose.

Basically, I need someone to make a valid Android package that has something we can scan in it.

Wikipedia has a reasonable description of what should be in the file: https://en.wikipedia.org/wiki/Apk_(file_format)

You could include a new library file into it with strings that will trigger a checker, or you could re-use a smaller existing file like https://github.com/intel/cve-bin-tool/blob/main/test/assets/test-curl-7.34.0.out and put it in an appropriate place in the apk then check for it in the scans.

Taking the good first issue off this flag because there's already a PR in progress so I don't want any other new folk to stumble over this.
