Updating conda does nothing, and wastes 16 seconds of the build.
Locally, this is about 2.5-3 times faster.
We re-use the same filename a lot, so we need a lock to prevent file I/O overlapping between processes when running tests in parallel.

Because we re-use filenames for tests, I added a lock using |

Rationale
Currently, Travis takes approximately 250s (4m10s) to install conda, cartopy, and its dependencies, 153s (2.5m) to run tests, and 5s for other bits.

Hopefully, this will get builds a bit closer to 5m.
