Eric Biggers 4d920ed684 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: 4a1c9e544b ("libbpf: remove linux/unaligned.h dependency for libbpf_sha256()")
