[Tile-serving] [osm2pgsql] Clean up after flat nodes tests (#458)

[Matt Amos]

The flat nodes tests each create 20GB flat nodes files and didn't remove them when the tests were finished, which would fail on my system which has "only" 35GB free disk space. This PR adds an RAII cleanup object to remove the files when the tests are complete, reducing the amount of disk space needed to "only" 20GB if the tests are run serially.
