Subject: [PATCH] add more //go:build directives to prevent downgrading to
 go1.16 language

This is a follow-up to 2cf230951fe29e2c2eda9eed43042524435c761a, adding
more directives to adjust for some new code added since:

Before this patch:

    make -C ./internal/gocompat/
    GO111MODULE=off go generate .
    GO111MODULE=on go mod tidy
    GO111MODULE=on go test -v

    # github.com/docker/docker/internal/sliceutil
    internal/sliceutil/sliceutil.go:3:12: type parameter requires go1.18 or later (-lang was set to go1.16; check go.mod)
    internal/sliceutil/sliceutil.go:3:14: predeclared comparable requires go1.18 or later (-lang was set to go1.16; check go.mod)
    internal/sliceutil/sliceutil.go:4:19: invalid map key type T (missing comparable constraint)

    # github.com/docker/docker/libnetwork
    libnetwork/endpoint.go:252:17: implicit function instantiation requires go1.18 or later (-lang was set to go1.16; check go.mod)

    # github.com/docker/docker/daemon
    daemon/container_operations.go:682:9: implicit function instantiation requires go1.18 or later (-lang was set to go1.16; check go.mod)
    daemon/inspect.go:42:18: implicit function instantiation requires go1.18 or later (-lang was set to go1.16; check go.mod)

With this patch:

    make -C ./internal/gocompat/
    GO111MODULE=off go generate .
    GO111MODULE=on go mod tidy
    GO111MODULE=on go test -v
    === RUN   TestModuleCompatibllity
        main_test.go:321: all packages have the correct go version specified through //go:build
    --- PASS: TestModuleCompatibllity (0.00s)
    PASS
    ok  	gocompat	0.031s
    make: Leaving directory '/go/src/github.com/docker/docker/internal/gocompat'
