Fix argument type for max() in graphics/gource

During the exp-run in bug 208158, it was found that graphics/gource gives errors with libc++ 3.8.0 [1]:

src/dirnode.cpp:585:27: error: no matching function for call to 'max'
    this->parent_radius = std::max(1.0, sqrt(total_file_area) * gGourceDirPadding);
                          ^~~~~~~~

This is because max() is being called with two arguments of different type (double and float).  Fix this by using 0.0f instead (and casting the result of sqrt to float like two lines above, though this should strictly not be necessary).

Please commit this.

(you may fix clang-3.8 errors for my ports without my approval in the future).

Thanks for your work!
