Subject: selftests/bpf: test_progs: remove global fail/success counts
Patch-mainline: v5.4-rc1
Git-commit: d38835b75f67df16cef65c14aa64796a1832e6b4
References: bsc#1155518
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.
