Subject: winrt: Use winsock2 API for hostname resolution on WinRT/WinPhone

That API has been available for WinRT and Windows
Phone for some time now. By using it to get the
machine name and for hostname resolution we can get
rid of some winrt-only code and use qhostinfo_win.cpp
on WinRT and Windows phone as well.

Additionally the required capability was added to
tst_qhostinfo so that this auto test can be run without
any manual editing.
