Revert "runtime: add a workaround for Windows build"

This reverts commit efaf1fb.
Add a much more palatable workaround for the unit tests.  Rather than
adding the dllimport for the symbols, locally define the required
symbols.  This list is sufficient to restore the ability to build tests
for Windows.
