Title: Add comment discussing the dangers of pacman -Sy

This is in response to #10519, the latest attempt to change how Salt calls pacman. This comes up from time to time, and it would be helpful to let people know beforehand why we use `-Syu` instead of just `-Sy`. Thanks for @gtmanfred for the link.
