[release/1.4.14] build: limit test concurrency

fjl · karalabe · commit 7c17a6704c3c · 2016-09-28T13:32:08.000+03:00
TravisCI and AppVeyor run the tests in very slow VMs. Some of our tests can't cope with that. Running less tests in parallel should make them somewhat less flakey. (cherry picked from commit b0a6b97)
