Ed Schouten 3f880912e9 Add 'ignore-cloudabi' to tests that don't and won't build on CloudABI.
It looks like many of these tests are already disabled on emscripten,
which also doesn't seem to support environment variables and subprocess
spawning. Just add a similar tag for CloudABI. While there, sort some of
the lists of operating systems alphabetically.
