osx: Fix iOS/macOS packaging by using normalized pkgconfig paths

While creating a framework for iOS and macOS, the code was performing
the following steps:

1. Fetch a list of all files in all recipes
2. Make a list of all include_dirs from pkg-config for all recipes
3. Copy files from the list of all files that are inside the
   include_dirs

(3) was literally doing a `foo in bar` substring check that was
failing because the include_dirs paths now contain relative path
components. Fix it by always returning absolute normalized paths
from the Pkgconfig module.
