Allow tests to run when min stack size is less than page size

We would like this to be possible under WebAssembly/emscripten
which has a pretty high page size (64k).

IIRC these check are really about saying that the tests have
not themselves been verified under such conditions and not about
the pthread spec containing such a requirement.

I verified that all these tests run fine with stack size of 2k
under emscripten.
