twrtp_jibuf_create: make config argument const

While this config structure is not a constant in the mathematical
sense of the term (it is expected that vty config changes may happen
while twjit instance is alive), twjit functions never write to it,
only read, hence it is 'const' in the not-quite-mathematical C-standard
sense.
