daniel d7bc6c5c91 legal: TCC and Lua license declarations 
- THIRD-PARTY-NOTICES.txt gains sections for the Tiny C Compiler
  (0.9.28rc, LGPL-2.1, modified for MontaukOS; source in
  programs/src/tcc/) and Lua (5.4.8, MIT, Lua.org PUC-Rio).
- LGPL-2.1 full text ships at 0:/os/licenses/LGPL-2.1.txt (copied from
  the vendored TCC COPYING); Lua's MIT text is reproduced in the
  notices file.
- Both components added to the license's third-party list and man legal.

MontaukOS - Third-Party Notices
===============================
The MontaukOS system is source-available software governed by the MontaukOS Software
License (see license.txt). It incorporates or is distributed together with the
third-party components listed below, each of which remains the property of its
respective owner and is provided under its own license. The notices and license
texts in this file apply only to the corresponding third-party component and not
to MontaukOS as a whole.
This file is provided to satisfy the attribution and redistribution conditions of
those licenses. Where a component permits a choice of license, MontaukOS relies on
the option reproduced here.
