libbpf: Replace AF_ALG with open coded SHA-256
Reimplement libbpf_sha256() using some basic SHA-256 C code. This
eliminates the newly-added dependency on AF_ALG, which is a problematic
UAPI that is not supported by all kernels.
Make libbpf_sha256() return void, since it can no longer fail. This
simplifies some callers. Also drop the unnecessary 'sha_out_sz'
parameter. Finally, also fix the typo in "compute_sha_udpate_offsets".
Fixes: c297fe3e9f99 ("libbpf: Implement SHA256 internal helper")
