client: do not disable memory swappiness if kernel does not support it (#17625)
* client: do not disable memory swappiness if kernel does not support it

This PR adds a workaround for very old Linux kernels which do not support
the memory swappiness interface file. Normally we write a "0" to the file
to explicitly disable swap. In the case the kernel does not support it,
give libcontainer a nil value so it does not write anything.

Fixes #17448

* client: detect swappiness by writing to the file

* fixup changelog
