Including the network_helpers.h header in tests can lead to the following
build error:

./network_helpers.h: In function ‘csum_tcpudp_magic’:
./network_helpers.h:116:14: error: implicit declaration of function \
  ‘htons’ [-Werror=implicit-function-declaration]
  116 |         s += htons(proto + len);

The error is avoided in many cases thanks to some other headers included
earlier and bringing in arpa/inet.h (ie: test_progs.h).

Make sure that test_progs build success does not depend on header ordering
by adding the missing header include in network_helpers.h
