dbscrips: make createlinks also work if filename contains spaces

This addresses the problem that so far the for loop recognizes each
filename with a space as different word, i.e.:

$ for f in $(find pkg.1 -type f); do echo "$f"; done
pkg.1/usr/bin/Surge
XT
Effects
pkg.1/usr/bin/Surge
XT

while the correct output would have been:
pkg.1/usr/bin/Surge XT Effects
pkg.1/usr/bin/Surge XT

We fix this by explictly passing each find result as its own variable.

fixes archlinux/infrastructure#524
