disable module loading after BOOT_COMPLETED broadcast
This CL disables module loading by writing 1 to
/proc/sys/kernel/modules_disabled when the property sys.boot_completed
is set to 1 by ActivityManagerService (at the broadcast of
PHASE_BOOT_COMPLETED).
Bug: 36515654
Test: tested on sailfish and verified that module loading is disabled in
userdebug and enabled in eng mode
