Add default port for the gopher: scheme.

KURL parsing uses known_ports.cc for supporting known ports for standard
schemes. GURL uses its own version, which leads to mismatch in behavior.

This CL adds gopher's default port to known_ports.cc, however a follow
up patch should just remove gopher support in general.
