dev-util/blueprint-compiler: Sync live ebuild for Py module path change

This is the third time the upstream changes where the package's Python
module is installed, yet it is merely a backtrack to pre-v0.2.0
behavior...

Nevertheless, the good news is that this package can be installed as a
multi-impl Python package (again).
