selftests/bpf: Fix test_core_autosize on big-endian machines
[ Upstream commit d164dd9a ] The "probed" part of test_core_autosize copies an integer using bpf_core_read() into an integer of a potentially different size. On big-endian machines a destination offset is required for this to produce a sensible result.
