Avoid use of v4-mapped QHostAddress::AnyIPv4 local address on Windows

Some Windows kernels return a v4-mapped QHostAddress::AnyIPv4 as a
local address of the socket which bound on both IPv4 and IPv6
interfaces. This address does not match to any special address and
should not be used to send the data.

To allow handling of the local addresses properly, replace it with
QHostAddress::Any.

Already tested by tst_qudpsocket.
