examples/tcpblaster: fix CMake build with GCC 14
With CMake, the tcpblaster host tool is built as part of the NuttX
build and uses the host C library headers. tcpblaster_server.c calls
accept4(), which glibc declares only when _GNU_SOURCE is defined, so
GCC 14 fails with "implicit declaration of function 'accept4'".
Define _GNU_SOURCE for the host tool in tcpblaster_host.cmake. The
Make build is not affected.
