doc, mm: clarify /proc/<pid>/oom_score value range

Browse source 
The exported value includes oom_score_adj so the range is no [0, 1000] as
described in the previous section but rather [0, 2000].  Mention that fact
explicitly.

@ -1676,6 +1676,9 @@ This file can be used to check the current score used by the oom-killer for
any given <pid>. Use it together with /proc/<pid>/oom_score_adj to tune which
process should be killed in an out-of-memory situation.
Please note that the exported value includes oom_score_adj so it is
effectively in range [0,2000].
