Fix: Make system/install.sh report what it did and stop adding blank lines

Browse Source 
Prints whether options.conf and the pacman.conf Include were installed or
already in place, then the options pacman ends up using. Dropping an old
Include now also drops the blank line written after it, so re-runs leave
pacman.conf untouched instead of adding a blank line and rewriting it.
