dev-python/brotlicffi: Incompatible rename of dev-python/brotlipy

This is the continuation of dev-python/brotlipy.  I am not doing a move
here since the rename (obviously) breaks all reverse dependencies,
and both old and new names are co-installable.  Good news is that this
removes the blocker on app-arch/brotli[python].
