Ensure generated source files are deterministic and reproducible

* mk-builtins.pl: Sort the list of dispatch types for built-in functions to
ensure that the contents of libinterp/builtins.cc are reproducible.

* mk-errno-list: Sort the list of system error codes in the embedded perl and
python scripts to ensure that the contents of libinterp/corefcn/oct-errno.cc
are reproducible.  Update the python script to be Python 3 compatible.
