Using cross compilation toolchains that work from any platform
Adds darwin/arm64 support and bake targets. Static and dynamic
binary targets are available, both with glibc and musl.

macOS doesn't ship with the GNU version of `date`, which
causes the command to fail if the `--rfc-3339 ns` format option
is used.
Given that we don't need the build-time with nanosecond precision,
this patch changes the format used, so that the CLI binary can be
built on the host (outside of a container);
Before this change, `make binary` would fail:
DISABLE_WARN_OUTSIDE_CONTAINER=1 make binary
WARNING: binary creates a Linux executable. Use cross for macOS or Windows.
./scripts/build/binary
make: *** [binary] Error 1
With this change, the binary can be built on the host:
DISABLE_WARN_OUTSIDE_CONTAINER=1 make binary
WARNING: binary creates a Linux executable. Use cross for macOS or Windows.
./scripts/build/binary
Building statically linked build/docker-darwin-amd64
While the previous version formatted (and parsed) the date with nanoseconds precision,
that level of precision is not actually used;
```go
func reformatDate(buildTime string) string {
t, errTime := time.Parse(time.RFC3339Nano, buildTime)
if errTime == nil {
return t.Format(time.ANSIC)
}
return buildTime
}
```
Both the old, and new input will yield the same output:
```go
fmt.Println(reformatDate("2019-12-31T13:41:44.846741804+00:00"))
// Tue Dec 31 13:41:44 2019
fmt.Println(reformatDate("2019-12-31T13:41:44Z"))
// Tue Dec 31 13:41:44 2019
```

This just makes it easier to build a targeted binary for the
goos/goach/goarm version.
This of course will not work for all cases but is nice to get things
going.
Specifically cross-compiling pkcs for yubikey support requires some
extra work whichis not tackled here.

This helps to avoid circular includes, by separating the pure data out from the
actual functionality in the cli subpackage, allowing other code which is
imported to access the data.

The Server section of version output is now composed of an Engine
component and potentially more, based on what the /version endpoint
returns.
