[27.x backport] info: stop printing "Expected" commits

[thaJeztah]

• backport info: stop printing "Expected" commits #5422

relates to:

• Add external binaries version to docker info moby/moby#27955
• Remove version-checks for containerd and runc moby/moby#37968
• info: remove "expected" check for tini version moby/moby#42776
• docker-ce_18.06.2 runc version is unexpected on ubuntu moby/moby#38739

The Commit type was introduced in moby/moby@2790ac6, to assist triaging issues that were reported with an incorrect version of runc or containerd. At the time, both runc and containerd were not yet stable, and had to be built from a specific commit to guarantee compatibility.

We encountered various situations where unexpected (and incompatible) versions of those binaries were packaged, resulting in hard to trace bug-reports. For those situations, a "expected" version was set at compile time, to indicate if the version installed was different from the expected version;

docker info
...
runc version: a592beb5bc4c4092b1b1bac971afed27687340c5 (expected: 69663f0bd4b60df09991c08812a60108003fa340)

Both runc and containerd are stable now, and docker 19.03 and up set the expected version to the actual version since moby/moby@c65f0bd and 23.0 did the same for the init binary moby/moby@b585c64, to prevent the CLI from reporting "unexpected version".

In short; the Expected fields no longer serves a real purpose, so we should no longer print it.
