Fix bunch of ports by TundraWare, which share a common set of problems

• Add LICENSE It explicitly requires user agreement (thus no-auto-accept) and forbids distribution for a fee beyond reasonable duplication charges which is too vague I don't think can be guaranteed in any case (thus no-*-sell)
  
  tdir port uses another variant of license, which also forbids modification, and since the port requires shebangfix and Makefile patching, also mark it no-pkg-mirror and BROKEN.

• Don't install licenses with documentation, since our license framework already handles this
• Fix python shebangs
• Limit python version to 2.7, as no port is compatible with python3
• Add NO_ARCH
• User options targets helpers
• Simplify installation in a few cases
