Subject: bpf: Remove inclusions of crypto/sha1.h

Since commit 603b44162325 ("bpf: Update the bpf_prog_calc_tag to use
SHA256") made BPF program tags use SHA-256 instead of SHA-1, the header
<crypto/sha1.h> no longer needs to be included.  Remove the relevant
inclusions so that they no longer unnecessarily come up in searches for
which kernel code is still using the obsolete SHA-1 algorithm.

Since net/ipv6/addrconf.c was relying on the transitive inclusion of
<crypto/sha1.h> (for an unrelated purpose) via <linux/filter.h>, make it
include <crypto/sha1.h> explicitly in order to keep that file building.
