Fix T38324: import SVG from Inkscape doesn't match space origin

Made some tweaks to transformation matrix of <svg> node to make
it so origin from Inkscape matches Blender origin.

Currently only affects files from Inkscape, for others it's not
so much clear what origin should be.

Based on the patch from aldero (juanC), thanks!
