Subject: [PATCH net-next 6/8] 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.

  Summary: 7 PASSED, 1 FAILED
  selftests: test_progs [PASS]
