Streamly core >= 0.2 does not build on FreeBSD

[sumo]

As per the defines build fails. Should there be anther package (streamly-io?) that provides IO related capability so that streamly-core can be used without a dependency on OS?

Building library for streamly-core-0.2.1..

This should be fixable, we do not have a FreeBSD CI, that's why this is not working.
