[LIBS - PART I] Initial refactor of library recipes (#1944)

This commit will introduce a new cls attribute: `built_libraries`.
This `built_libraries` attribute must be a dictionary. The keys are the full library name, e.g.: `libffi.so`. And the values must be the relative path of the library, e.g: `.libs`. So the this cls attribute for libffi recipe it would look like:
    ```built_libraries = {'libffi.so': '.libs'}```

This new cls attribute will allow us to detect library recipes and to refactor common operations that we do for those kind of recipes:
  - copy library into right location
  - implement `should_build` for library recipes

Those two things will make that our rebuilds to be more consistent and I hope that it will be easier to maintain. 

**So, once explained a little this PR, in here we do:**
  - [x] Add attribute `built_libraries`
  - [x] Add methods to refactor common library operations:
    - [x] install_libraries
    - [x] get_libraries
  - [x] implement `should_build` for library recipes
  - [x] implement basic tests for the newly introduced `Recipe` methods
  - [x] Make use of those Library attributes/methods for some basic set of recipes:
    - [x] libffi
    - [x] openssl
    - [x] png
    - [x] jpeg
    - [x] freetype
    - [x] harfbuzz
    - [x] libcurl
    - [x] libzbar
    - [x] libiconv
    - [x] libexpat
    - [x] libogg
    - [x] libxml2
    - [x] libxslt
    - [x] libshine
    - [x] libx264
    - [x] libglob
    - [x] libsodium
    - [x] libsecp256k1

**Things to do in separate PRs**, to be easy to review and because those points will start to conflict with the `NDK r19 migration` thing just merged:
  - Make use of Library attributes/methods introduced in this PR for un covered library recipes in here. Here we have two situations:
     - library recipes that depends on android's STL library (almost all the work done in here will depend of the `NDK r19 migration` thing)
     - all r... (continued)
