This bumps go.mod to the current tailscale/golang-x-crypto, picking up
its rebase onto current upstream golang.org/x/crypto and its
cherry-pick of the pending upstream change
https://go-review.googlesource.com/c/crypto/+/788000, which adds ACME
certificate profile support: a new WithOrderProfile order option and
profile discovery via the directory metadata. That change has not yet
been submitted upstream and is subject to final API changes before it
lands there.
It then re-vendors that fork's acme package into tempfork/acme as
usual (per the TestSyncedToUpstream workflow), except for upstream's
pebble_test.go, which is now excluded from the sync: its
TestWithPebble downloads the Pebble module from outside our go.mod,
then builds and runs its binaries during tests.
Profile support is needed to request LetsEncrypt IP address
certificates, which require the "shortlived" profile.

We've been maintaining temporary dev forks of golang.org/x/crypto/{acme,ssh}
in https://github.com/tailscale/golang-x-crypto instead of using
this repo's tempfork directory as we do with other packages. The reason we were
doing that was because x/crypto/ssh depended on x/crypto/ssh/internal/poly1305
and I hadn't noticed there are forwarding wrappers already available
in x/crypto/poly1305. It also depended internal/bcrypt_pbkdf but we don't use that
so it's easy to just delete that calling code in our tempfork/ssh.
Now that our SSH changes have been upstreamed, we can soon unfork from SSH.
That leaves ACME remaining.
This change copies our tailscale/golang-x-crypto/acme code to
tempfork/acme but adds a test that our vendored copied still matches
our tailscale/golang-x-crypto repo, where we can continue to do
development work and rebases with upstream. A comment on the new test
describes the expected workflow.
While we could continue to just import & use
tailscale/golang-x-crypto/acme, it seems a bit nicer to not have that
entire-fork-of-x-crypto visible at all in our transitive deps and the
questions that invites. Showing just a fork of an ACME client is much
less scary. It does add a step to the process of hacking on the ACME
client code, but we do that approximately never anyway, and the extra
step is very incremental compared to the existing tedious steps.
