os: fix TestChdirAndGetwd/ReaddirnamesOneAtATime on wasip1 to run on Windows hosts

TestReaddirnamesOneAtATime and TestChdirAndGetwd assumes the underlying file system
has /usr/bin but it is not the case when running it on WASI runtime hosted on Windows.

This change adds wasip1 in the special cased switch case to make them host OS agonstic.
