elfmalloc: Re-enable Travis tests, set RUST_TEST_THREADS=1 #167

We've previously had an issue with running out of memory during Travis tests, so this PR forces the tests to run sequentially to reduce the maximum working set size and reduces the size of certain tests when running in Travis via the low-memory-tests feature.
