Add support for oom_score_adj
/proc/<pid>/oom_adj has been deprecated (kernel v2.6.36) due to the
rework of the badness heuristic; oom_score_adj is the replacement.
Keep a fallback to the old interface for compatibility with older
kernels.
See http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=a63d83f427fbce97a6cea0db2e64b0eb8435cd10
