with the command you've used only 'gdk-pixbuf-query-loaders' was run as sudo and the redirection of the output to /usr/lib/x86_64-linux-gnu/... was done as yourself.

Try sudo -i to start a root prompt then run:

gdk-pixbuf-query-loaders > /usr/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/2.10.0/loaders.cache

Then logout as root.
