-Dbpf_prog_load_deprecated=bpf_prog_test_load trick is both ugly and
breaks when deprecation goes into effect due to macro magic. Convert all
the uses to explicit bpf_prog_test_load() calls which avoid deprecation
errors and makes everything less magical.

1. Move pkt_v4 and pkt_v6 into network_helpers and adjust the users.
2. Copy-paste spin_lock_thread into two tests that use it.

Now that we have a global per-test/per-environment state, there
is no longer need to have global fail/success counters (and there
is no need to save/get the diff before/after the test).
Introduce CHECK_FAIL macro (suggested by Andrii) and covert existing tests
to it. CHECK_FAIL uses new test__fail() to record the failure.

The test_progs subtests, test_spin_lock() and test_map_lock(),
requires BTF present to run successfully.
Currently, when BTF failed to load, test_progs will segfault,
$ ./test_progs
...
12: (bf) r1 = r8
13: (85) call bpf_spin_lock#93
map 'hash_map' has to have BTF in order to use bpf_spin_lock
libbpf: -- END LOG --
libbpf: failed to load program 'map_lock_demo'
libbpf: failed to load object './test_map_lock.o'
test_map_lock:bpf_prog_load errno 13
Segmentation fault
The segfault is caused by uninitialized variable "obj", which
is used in bpf_object__close(obj), when bpf prog failed to load.
Initializing variable "obj" to NULL in two occasions fixed the problem.
$ ./test_progs
...
