Set lowmemorykiller kernel driver parameters before lmkd is started
When kernel lowmemorykiller driver is enabled lmkd detects it by
checking write access to /sys/module/lowmemorykiller/parameters/minfree
parameter. By default this file does not have write access and init
process changes that from "on boot" section of init.rc. However
"on boot" is never executed in the charger mode, therefore lmkd fails
to detect the kernel driver. Fix this by setting lowmemorykiller kernel
driver parameters before lmkd is started.
Bug: 148572711
Test: boot into charger mode with kernel lmk driver enabled
