Timo Kaufmann 6359e9baf0 python3.pkgs.tinycss: fix build ()
The build was broken by the python 3.7 switch, which caused an
incompatible change in the way cython generates files:

https://github.com/Kozea/tinycss/issues/17

This is solved by removing the pre-generated file and re-generating it
at build time.
