bpf: Use sha1() instead of sha1_transform() in bpf_prog_calc_tag()

Now that there's a proper SHA-1 library API, just use that instead of
the low-level SHA-1 compression function.  This eliminates the need for
bpf_prog_calc_tag() to implement the SHA-1 padding itself.  No
functional change; the computed tags remain the same.
