Fixed ipsec pool --batch command

--batch mode has shown to be buggy in very obscure ways in the first real
life tests. For example a batch file

       --del pool1
       --replace pool2 --addresses file1

returned the error "/usr/libexec/ipsec/pool: unrecognized option '--lace'"
which was gone after moving the --del behind --replace. With the patch
from below applied everything works like a charm. From the info on the
man page it seem to be unrelated to this problem, though:

       A program that scans multiple  argument  vectors,  or
       rescans  the same vector more than once, and wants to
       make use of GNU extensions such as '+' and '-' at the
       start   of   optstring,   or  changes  the  value  of
       POSIXLY_CORRECT  between  scans,  must   reinitialize
       getopt()  by  resetting  optind to 0, rather than the
       traditional value of 1.  (Resetting to 0  forces  the
       invocation of an internal initialization routine that
       rechecks POSIXLY_CORRECT and checks  for  GNU  exten-
       sions in optstring.)
