oom_score_adj must be in the range -1000 to 1000. In AdjustOOMScore if containerd's score is already at the maximum value we should set that value for the shim instead of trying to set 1001 which is invalid.

This allows non-privileged users to use containerd.
If a non root user tried to set a negative oom score adjustment,
it will fail. Containerd should not fail if running rootless.
This is part of a larger track of work integrating containerd
into Cloudfoundry's garden with support for rootless.

This adds a config option to set the oom score for the containerd daemon
as well as automatically setting the oom score for the shim's lauched so
that they are not killed until the very end of an out of memory
condition.
