(Win32) Fixed link error apr_pstrmemdup in flood_socket_keepalive.c.

This patch addresses a link error.  The code invoked apr_pstrmemdup()
in flood_socket_keepalive.c without including the proper declaration.
The compiler generates its own guess, which is incorrect.  The code now
includes the file:
  apr_strings.h
so that it picks up the proper declaration of apr_pstrmemdup.

Below are examples of the compile-time warning and the
link failures that this patch addresses.

  flood_socket_keepalive.c(407) : warning C4013: 'apr_pstrmemdup'
  undefined; assuming extern returning int
  flood_socket_keepalive.obj : error LNK2001: unresolved external
  symbol _apr_pstrmemdup
