fix: Fix enable/disable-profiling flag (#1018)

The variable enable_profiling exists just because AC_ARG_ENABLE([profiling] is defined.
If it is redefined in the exist condition, the both enable and disable flags will enable the profiling,
just if the flag is missing it will be disabled.

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.

Allow disabling auto-detect of SCTP (#1008)

* feat: Add a mechanism to disable checks for SCTP (--without-sctp).

The use case for this is building a static iperf3 binary on CentOS 7,
on a system with SCTP installed (but it has no static SCTP libraries).
In that case we need to disable SCTP detection to prevent a linking
error at runtime.

While here, s/iperf /iperf3 / in a couple of help strings.
