lowmem: Split up governor from lowmem module
The lowmem-governor.c was created by extracting the
"sorting out kill candidate" functionality from lowmem.c.
* Newly created: lowmem-governor.c, lowmem-governor.h
* "lowmem_governor_get_kill_candidates" function from
lowmem-governor.c gets a list of procs/apps and returns a sorted
list of kill candidates.
* Functions that only used in lowmem-governor.c were moved into
lowmem-governor.c from lowmem.c.
