scons: Make debug build default.

I've been back and forth on this, but I believe it's worth to have debug
by default.

Most humans (developers, testers) will want to use the debug version  by
default.  Many build bots want release but they are bots, and humans >
bots, so I don't care that much.

This is part of my initiative of minimizing the scons option mess many
complain about.
