tcpreplay: fix build error with gcc-15

There are two types of errors:
1. Linker errors for txring.c

The txring file needs to include config.h to build properly.
Surprisingly, in the same environment with gcc14, HAVE_TX_RING is not declared in config.h because it fails during the configure stage.

The config.log below is from the same environment with gcc14.
configure:26549: result: no
configure:26557: checking for TX_RING socket sending support
configure:26579: conftest.c >&5
In file included from conftest.c:130:
/linux/if_packet.h:14:8: error: redefinition of 'struct sockaddr_ll'
   14 | struct sockaddr_ll {
      |        ^~~~~~~~~~~
Therefore, it seems that the linker error did not occur previously.

2. Incompatible type assignment in txring.c when allocating memory for txring_t structure

+- The result of "nm -u txring.o" shows no symbols exist.
+
+- The config.h has HAVE_TX_RING defined but txring.c is not aware of it.
+  txring.c and txring.h include config.h at the beginning.
+
+- This resulted in a successful build in my build environment.
