utils_netperf: bypass compilation failure

Starting from gcc 14.0, implicit function declarations are treated as errors by default [1], which caused the following failure been observed during the compilation. > netlib.c:2343:9: error: implicit declaration of function ... > ... > make[3]: *** [Makefile:454: netlib.o] Error 1 One contributor has already sent a PR [2] to fix the issue to the netperf upstream, however, it has not been merged yet since a year ago. At the moment, let's just bypass this issue, while waiting for a regular fix to be done.
