Subject: [PATCH] mavproxy: add lxml dependency

Also, alphabetize the dependencies.

Add dependencies that are not part of install_requires (apparently due to
some issue with pip and distro packaging). The closure size is increased
somewhat by OpenCV, but this allows all the tools to work correctly.
