test-util: drop _packed_ attribute

gcc-9 warns:
../src/test/test-util.c:147:19: note: in expansion of macro ‘container_of’
  147 |         assert_se(container_of(&myval.v1, struct mytype, v1) == &myval);
      |                   ^~~~~~~~~~~~

I don't think packing matters here for the test of container_of(), so let's
just remove it.
