lmkd: handle missing process' information case
...
When we get nothing from /proc/<PID>/status and /proc/<PID>/cmdline,
we should return NULL or False because this usually indicates the
process has already terminated. We should avoid attempting
to kill a non-existent process, as it's an unnecessary waste
of kill timeout.

Experiments on low-RAM devices indicate regressions due to the new low
memory kill reason which cause LMKD to kill too many processes. Change
ro.lmk.lowmem_min_oom_score to disable kills for this reason by default.

lmkd: introduce lowmem_min_oom_score tunable
...
Current lmkd behavior to kill cached apps when free memory hits low
watermark threshold does not work well on certain devices where more
or less aggressive behavior would yield better results. Introduce a
tunable to control the min oom_score_adj level at which lmkd considers
to kill processes when the system gets into this state. The default
value is set to 701 which preserves the current behavior of killing
cached apps except for the last active one. Setting it to lower values
will make more processes eligible to be killed, setting it to higher
values will limit the kills to a smaller set of processes. Setting it
to 1001 will prevent any process from being killed for this reason.
