libbpf: Fix undefined behavior in {get,put}_unaligned_be32()
These violate aliasing rules and may be miscompiled unless
-fno-strict-aliasing is used. Replace them with the standard memcpy()
solution. Note that compilers know how to optimize this properly.
Fixes: 4a1c9e544b8d ("libbpf: remove linux/unaligned.h dependency for libbpf_sha256()")
