BUG/MINOR: payload: the patterns of the acl "req.ssl_ver" are no parsed with the good function.

The fetch "req.ssl_ver" is not declared as explicit acl. If it is used
as implicit ACL, the acl engine detect SMP_T_UINT output type and choose
to use the default interger parser: pat_parse_int(). This fetch needs the
parser pat_parse_dotted_ver().

This patch declare explicit ACL named "req.ssl_ver" that use the good
parser function pat_parse_dotted_ver().
