Fix warning: "HAVE_SCTP" redefined (#1010)

The netinet/sctp.h header file defines HAVE_SCTP, so we have this
warning while building:

    In file included from ../../src/iperf.h:30,
                     from ../../src/iperf_sctp.c:46:
    ./iperf_config.h:44: warning: "HAVE_SCTP" redefined
       44 | #define HAVE_SCTP 1
          |
    In file included from ../../src/iperf_sctp.c:43:
    /usr/include/netinet/sctp.h:56: note: this is the location of the previous definition
       56 | #define HAVE_SCTP
          |

This patch replaces our HAVE_SCTP definition with HAVE_SCTP_H to avoid
this warning.
