golangci-lint: temporarily disable G115: integer overflow conversion

it produces many hits, some of which may be false positives, but we need to
look into these, e.g.;

    container/container.go:517:72: G115: integer overflow conversion int -> uint32 (gosec)
        shouldRestart, _, _ := container.RestartManager().ShouldRestart(uint32(container.ExitCode()), container.HasBeenManuallyStopped, container.FinishedAt.Sub(container.StartedAt))
                                                                              ^
    container/view.go:401:25: G115: integer overflow conversion int -> uint16 (gosec)
                        PrivatePort: uint16(p),
                                           ^
    container/view.go:413:25: G115: integer overflow conversion int -> uint16 (gosec)
                        PrivatePort: uint16(p),
                                           ^
    container/view.go:414:25: G115: integer overflow conversion int -> uint16 (gosec)
                        PublicPort:  uint16(h),
                                           ^
