[PATCH bpf-next v2] bpf: Remove inclusions of crypto/sha1.h

[Eric Biggers]

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.
