python-grako: fix template

"The only dependencies are on the Python standard library, yet the regex
library will be used if installed, and colorama will be used on trace
output if available. pygraphviz is required for generating diagrams."

Note: grako is dead. See https://bitbucket.org/neogeny/grako.
