[yocto] Creating a recipe for python3-pillow

[Burton, Ross]

So the native recipe-sysroot-native is used for stuff that is actually
ran during the build, like Python, or gcc.  The target recipe-sysroot
is target libraries.

Note how it started by saying it found jpeglib.h in /usr/include, you
certainly don't want that so this auto-detection is really badly
coded.  Can you tell it where to look explicitly?
