selftests/bpf: Fix test_core_autosize on big-endian machines

[ Upstream commit d164dd9a5c08c16a883b3de97d13948c7be7fa4d ]

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.
