SourcePackageRecipe classes should move from soyuz

[Michael Nelson]

The following code really belongs under lp.code:

./lib/lp/soyuz/tests/test_sourcepackagerecipebuild.py
./lib/lp/soyuz/tests/test_sourcepackagerecipe.py
./lib/lp/soyuz/tests/test_recipebuilder.py
./lib/lp/soyuz/interfaces/sourcepackagerecipe.py
./lib/lp/soyuz/interfaces/sourcepackagerecipebuild.py
./lib/lp/soyuz/model/sourcepackagerecipe.py
./lib/lp/soyuz/model/sourcepackagerecipebuild.py
./lib/lp/soyuz/model/recipebuilder.py
./lib/lp/soyuz/model/sourcepackagerecipedata.py

I know, we all own the code, but it'll just allow bugs against the right projects etc.

Before exporting the recipes and adding more tests, I'll do this now.
