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.
