win32: Remove wsock32 from the list of libraries to link

Commit 5dddf7c8 (Add block-sha1 in favour of the mozilla routines
2010-04-14) introduced the "bswap.h" header file which, for x86
or x86-64 machines, provides a "sane" implementation of ntohl()
and htonl().

The wsock32 library, on the msvc and MinGW build, is only included
in the link to supply the ntohl()/htonl() routines.  Since we now
have a built-in implementation, we can remove the wsock32 library
from the link.

[This will break a Windows build on a non-intel machine]
