win: fix collecting DNS exclude data

The size of the returned MULTI_SZ wide domains string was calculated
wrongly. Instead of adding the size of a WCHAR, only the size of a char
was used. As a result, the domains string was stored too short and was
missing the final string terminator.

DHCP assigned DNS server addresses are separated by space, not comma.
These spaces were not replaced by semicolon, as the spec requires.
