Bicycle icon in lane images - more copyright paranoia

@westnordost Do you remember source of bicycle image used for example in https://github.com/streetcomplete/StreetComplete/blob/master/res/graphics/cycleway/none_no_oneway.svg ?

I admit that it is likely PD-shape anyway, but if you remember that you made it on your own or remember its source that would make it even easier.

It's the white version of the yellow bicycle from the quest icon. In other words, I made it myself.
