The sockets used by udpgso_bench_tx aren't always ready when
udpgso_bench_tx transmits packets. This issue is more prevalent in -rt
kernels, but can occur in both. Replace the hacky sleep calls with a
function that checks whether the ports in the namespace are ready for
use.

There are some issues with the bpf/nat6to4.c building.
1. It use TEST_CUSTOM_PROGS, which will add the nat6to4.o to
kselftest-list file and run by common run_tests.
2. When building the test via `make -C tools/testing/selftests/
TARGETS="net"`, the nat6to4.o will be build in selftests/net/bpf/
folder. But in test udpgro_frglist.sh it refers to ../bpf/nat6to4.o.
The correct path should be ./bpf/nat6to4.o.
3. If building the test via `make -C tools/testing/selftests/ TARGETS="net"
install`. The nat6to4.o will be installed to kselftest_install/net/
folder. Then the udpgro_frglist.sh should refer to ./nat6to4.o.
To fix the confusing test path, let's just move the nat6to4.c to net folder
and build it as TEST_GEN_FILES.

After commit afef88e655 ("selftests/bpf: Store BPF object files with
.bpf.o extension"), we should use xdp_dummy.bpf.o instade of xdp_dummy.o.
In addition, use the BPF_FILE variable to save the BPF object file name,
which can be better identified and modified.

In some conditions, background processes in udpgro don't have enough
time to set up the sockets. When foreground processes start, this
results in the test failing with "./udpgso_bench_tx: sendmsg: Connection
refused". For instance, this happens from time to time on a Qualcomm
SA8540P SoC running CentOS Stream 9.
To fix this, increase the time given to background processes to
complete the startup before foreground processes start.

When NET_F_F_GRO_FRAGLIST is enabled and bpf_skb_change_proto is used,
check if udp packets and tcp packets are successfully delivered to user
space. If wrong udp packets are delivered, udpgso_bench_rx will exit
with "Initial byte out of range"
