[apparmor] [PATCH] apparmor: fix endianness of test data in policy_unpack_test

[Benjamin Gray]

The test data numbers are expected to be in little endian format
based on how the tests interact with them, but currently are
generated using host endianness. This causes several KUnit tests
to fail when booting a big endian kernel, e.g.

  # policy_unpack_test_unpack_array_with_null_name: EXPECTATION FAILED at security/apparmor/policy_unpack_test.c:151
  Expected array_size == (u16)16, but
      array_size == 4096 (0x1000)
      (u16)16 == 16 (0x10)
