selftests/bpf: fix test_align
since commit 82abbf8d2fc4 the verifier rejects the bit-wise
arithmetic on pointers earlier.
The test 'dubious pointer arithmetic' now has less output to match on.
Adjust it.
Fixes: 82abbf8d2fc4 ("bpf: do not allow root to mangle valid pointers")

selftests/bpf: add test for bogus operations on pointers
Tests non-add/sub operations (AND, LSH) on pointers decaying them to
unknown scalars.
Also tests that a pkt_ptr add which could potentially overflow is rejected
(find_good_pkt_pointers ignores it and doesn't give us any reg->range).

selftests/bpf: add a test to test_align
New test adds 14 to the unknown value before adding to the packet pointer,
meaning there's no 'fixed offset' field and instead we add into the
var_off, yielding a '4n+2' value.

selftests/bpf: rewrite test_align
Expectations have changed, as has the format of the logged state.
To make the tests easier to read, add a line-matching framework so that
each match need only quote the register it cares about. (Multiple
matches may refer to the same line, but matches must be listed in
order of increasing line.)

bpf: allow to specify log level and reduce it for test_verifier
For the test_verifier case, it's quite hard to parse log level 2 to
figure out what's causing an issue when used to log level 1. We do
want to use bpf_verify_program() in order to simulate some of the
tests with strict alignment. So just add an argument to pass the level
and put it to 1 for test_verifier.

selftests/bpf: make correct use of exit codes in bpf selftests
The selftests depend on using the shell exit code as a mean of
detecting the success or failure of test-binary executed. The
appropiate output "[PASS]" or "[FAIL]" in generated by
tools/testing/selftests/lib.mk.
Notice that the exit code is masked with 255. Thus, be careful if
using the number of errors as the exit code, as 256 errors would be
seen as a success.
There are two standard defined exit(3) codes:
/usr/include/stdlib.h
#define EXIT_FAILURE 1 /* Failing exit status. */
#define EXIT_SUCCESS 0 /* Successful exit status. */
Fix test_verifier.c to not use the negative value of variable
"results", but instead return EXIT_FAILURE.
Fix test_align.c and test_progs.c to actually use exit codes, before
they were always indicating success regardless of results.

bpf, tests: set rlimit also for test_align, so it doesn't fail
When running all the tests, through 'make run_tests', I had
test_align failing due to insufficient rlimit. Set it the same
way as all other test cases from BPF selftests do, so that
test case properly loads everything.
