sysutils/tree: provide fallback download URL and other improvements

- For some reason, upstream distfile site is currently inaccessible
  in certain parts of the world, e.g. Russia
- Pass build-related variables down to inner Makefile via MAKE_ARGS
  and remove the patch file (particularly, it was patching `install'
  target which is useless as the port is using its own)
- Adjust LICENSE (it's GPLv2 or later) and install documentation in
  the dedicated helper target (also install TODO file while here)
