Potentially version-dependent logic for determining if a container is privileged

[oshaked1]

When checking if a container is privileged in the docker ps plugin, the capabilities value is compared to 0x3fffffffff. This value represents all available capabilities on modern kernels that were tested, but it may be different on older (and even future) kernels.
I suggest performing a version-independent check, where instead of comparing to a static value, the container's capabilities are compared to the capabilities of the init task (PID 1), which must be privileged.
