this adds upstream PR #74

after
https://github.com/getlantern/systray/commit/5fb0feca3c0677e9fa31e579ff69631f49a379a2
was merged, we don't need to keep using the vendoring of systray.

there is some flickering with the stop/start/cancel menu items
chening their orderning that still needs to be solved.

- Resolves: #26

Stop generating one file in /tmp for each icon change. Let's move the
clean up to the set icon instead of waiting for the quit clean up.
Unlink will remove the file from /tmp, but app_indicator will hold a
descriptor until it finishes with it.

This is a cherry-pick from a pull-request upstream:
https://github.com/getlantern/systray/pull/63

- Resolves: #60
