zstreamtest : disabled multi-threading tests with --newapi --no-big-tests

Browse Source 
--no-big-tests is typically used in combination with qemu-user-static
qemu-user-static allocated 4 GB of RAM upfront.
On 2 GB VM, this can degenerate into a crash.
It's not a problem as long as memory is not used.
But with multi-threading enabled, memory fragmentation kicks in,
so the amoung of RAM effectively touched increases,
and can pass beyond the 2 GB limit of the VM.

In single-threaded mode, there is no such issue :
memory requirement is smaller, and remains well-located,
so very little fragmentation is expected.

This modification should make `qemu-arm-static zstreamtests --newapi --no-big-tests`
work fine on Travis CI.
