Set security update label in framework 

GmsCore will use different filenames to distinguish a security update
from a normal update. (update.zip for normal update and update_s.zip for
security update.) So, if framework observes the filename as
"update_s.zip", write command "--security" to BCB. This cmd ask the
recovery image to choose the right background string for update.
