  Log Message:
  -----------
  tolua: Generate deterministic code

Lua 5.2 and later seed their string hash function randomly,
so the pairs() iteration order over the usertype and collect
tables changes with every tolua run. tolua_reg_types() listed
usertypes in that varying order, making generated code and
freeciv binaries built from it differ between builds.

Sort the tables before writing them out, and drop the timestamp
from generated header files.

This change makes the freeciv package build reproducibly.

See https://reproducible-builds.org/ for why this matters.

See RM #2122
