iperf2: Fix build with latest libc++

Part of this patch was already there for gcc6 fix which was subsequenty
dropped in past iperf2 upgrades therefore
bring it back see 0647b7d6400b1c40fc6cb40596e56b852ceb85c5

Additionally check for stdbool.h being present on system

helps in fixing  build with latest clang/libc++

+Subject: [PATCH] Detect bool definition considering stdbool.h being present
+
+This helps in defining the value correctly on different platforms e.g.
+clang/libc++ depends on the definition coming from stdbool.h
+current builds fail to compile therefore
