add scipy/lapack CI tests

[mzakharo]

Adding CI tests for downloading and extracting LEGACY_NDK , gfortran to build lapack/scipy. Follow-up PR to #2615

[AndreMiras]

Awesome! Great effort thank you 🙏
@misl6 feel free to merge if you're happy with it too

As said on Discord, looks absolutely fine to me to add a test regarding scipy as it requires a specific NDK configuration to build. Yeah, it takes some additional (in parallel) time to build, but could be optimized later.

But, before merge, how about adding a testcase on on_device_unit_tests test app that does an actual (nothing so fancy) unittest when the test app is launched?
That would be really helpful to check that everything really worked as expected, and that scipy also works on runtime.

ATM, when ubuntu-latest-sdl2_scipy-bdist_unit_tests_app-debug-1.1-.apk is launched on a device, the following log is produced, and then the app immediately crashes:

@misl6 :can you please help understand what is the behaviour you expect to see?

The test that you just added is probably already targeting our need, but we usually expect to have an app that shows the test results on the device where the testapp is running, so we can avoid inspecting the logs via adb (even if is a good idea to keep adb enabled while doing tests).

When building with sdl2 as a bootstrap, kivy is mandatory to show results.

This is what we expect on sdl2+kivy testapp:

Something similar is also shown when using webview as a bootstrap for the testapp:

Ok, added kivy to the dep list, I now get the screen

LGTM! Thank you!
