test_prog's prog_tests/verifier_log.c is superseding test_verifier_log
stand-alone test. It cover same checks and adds more, and is also
integrated into test_progs test runner.
Just remove test_verifier_log.c.

We have switched to memcg-based memory accouting and thus the rlimit is
not needed any more. LIBBPF_STRICT_AUTO_RLIMIT_MEMLOCK was introduced in
libbpf for backward compatibility, so we can use it instead now. After
this change, the header tools/testing/selftests/bpf/bpf_rlimit.h can be
removed.
This patch also removes the useless header sys/resource.h from many files
in tools/testing/selftests/bpf/.

Unify memlock handling into bpf_rlimit.h and replace all occurences
in BPF kselftests with it.

The default rlimit RLIMIT_MEMLOCK is 64KB. In certain cases,
e.g. in a test machine mimicking our production system, this test may
fail due to unable to charge the required memory for prog load:
# ./test_verifier_log
Test log_level 0...
ERROR: Program load returned: ret:-1/errno:1, expected ret:-1/errno:22
Changing the default rlimit RLIMIT_MEMLOCK to unlimited makes
the test always pass.

Add a test for verifier log handling. Check bad attr combinations
but focus on cases when log is truncated.
