Fix static initialization order problem in windows-nat.c

Browse Source 
This patch fixes a static initialization order problem in
windows-nat.c that was pointed out by Jon Turney.  The underlying
problem is that the windows_nat_target constructor relies on
serial_logfile already being constructed, but this is not enforced by
C++ rules.  This patch fixes the problem by initializing the global
windows_nat_target later.
