scripts/build: make sure build-time is in UTC 

Before this:

    SOURCE_DATE_EPOCH=1606660000 DISABLE_WARN_OUTSIDE_CONTAINER=1 make binary
    ...
    + go build -o build/docker-darwin-amd64 -tags ' osusergo pkcs11' -ldflags ' -w -X "github.com/docker/cli/cli/version.GitCommit=090dd58dc" -X "github.com/docker/cli/cli/version.BuildTime=2020-11-29T15:26:40Z" -X "github.com/docker/cli/cli/version.Version=20.10.2-590-g090dd58dc"' -buildmode=pie github.com/docker/cli/cmd/docker
    ...

    make -f docker.Makefile shell
    SOURCE_DATE_EPOCH=1606660000 make binary
    ...
    + go build -o build/docker-linux-amd64 -tags  -ldflags ' -w -X "github.com/docker/cli/cli/version.GitCommit=090dd58dc" -X "github.com/docker/cli/cli/version.BuildTime=2020-11-29T14:26:40Z" -X "github.com/docker/cli/cli/version.Version=20.10.0-dev"' github.com/docker/cli/cmd/docker
    ...

Notice that `version.BuildTime` is `2020-11-29T15:26:40Z` outside the container,
and `2020-11-29T14:26:40Z` inside.

After this:

    SOURCE_DATE_EPOCH=1606660000 DISABLE_WARN_OUTSIDE_CONTAINER=1 make binary
    ...
    + go build -o build/docker-darwin-amd64 -tags ' osusergo pkcs11' -ldflags ' -w -X "github.com/docker/cli/cli/version.GitCommit=090dd58dc" -X "github.com/docker/cli/cli/version.BuildTime=2020-11-29T14:26:40Z" -X "github.com/docker/cli/cli/version.Version=20.10.2-590-g090dd58dc.m"' -buildmode=pie github.com/docker/cli/cmd/docker
    ...

    make -f docker.Makefile shell
    SOURCE_DATE_EPOCH=1606660000 make binary
    ...
    + go build -o build/docker-linux-amd64 -tags  -ldflags ' -w -X "github.com/docker/cli/cli/version.GitCommit=090dd58dc" -X "github.com/docker/cli/cli/version.BuildTime=2020-11-29T14:26:40Z" -X "github.com/docker/cli/cli/version.Version=20.10.0-dev"' github.com/docker/cli/cmd/docker
    ...

Notice that `version.BuildTime` is `2020-11-29T14:26:40Z` both outside and inside
the container.
