small change in python-compat.h (for win32)

[Alexander Belchenko]

dirstate_helpers extension linked with winsock2 dll on windows.

if sys.platform == 'win32':
     add_pyrex_extension('bzrlib._dirstate_helpers_c',
                         libraries=['Ws2_32'])

But python-compat.h uses header from winsock1 library.
It does not harm actually, but IMO there should be consistency.

Here is proposed small one-line change:
