- Runtime: adapt cgroup capability detection to work on Gentoo

+ Add initial Changelog

On Gentoo, the memory cgroup is mounted at /sys/fs/cgroup/memory, but the mount line looks like the following:
memory on /sys/fs/cgroup/memory type cgroup (rw,nosuid,nodev,noexec,relatime,memory)

(note that the first word on the line is "memory", not "cgroup", but the other essentials are there, namely the type of cgroup and the memory mount option)

453 generic kernel detection fix

README.md: `docker port` instead of just `port`

Fix typo (ghot -> ghost)

Update utils.go to not enforce extra constraints on the kernel "flavor" (such as being integral or even comparable one to another)

Update utils.go to not enforce extra constraints on the kernel "flavor" (such as being integral or even comparable one to another)

This is especially to fix the current docker on kernels such as gentoo-sources, where the "flavor" is the string "gentoo", and that obviously fails to be converted to an integer.
