dev-util/scons: Bump to 3.0.3

Bump to upstream 3.0.3 release now that they managed to push the tag.
If anyone wants 3.0.4, then please contact upstream to figure out
whether they actually made that release already, and if they did, then
please kindly ask them to start pushing tags after doing releases.
