  Fix unreachable nc portability shim
  
  This fixes nc failing to run on darwin due to it incorrectly setting the
  linux-specific SOCK_NONBLOCK flag on connect.
  
  nc already had a portability shim in apps/nc/compat/sys/socket.h, which
  kicks in if SOCK_NONBLOCK is undefined. But that header includes
  include/compat/sys/socket.h, which also has a portability shim that
  defines a default value for SOCK_NONBLOCK if it's undefined. Thus the
  first portability shim was unreachable.
  
  Fixes this by moving the NEED_SOCKET_FLAGS flag into the outer shim, and
  having the inner shim activate if NEED_SOCKET_FLAGS is defined.
  
  This closes https://github.com/libressl-portable/portable/issues/631
