run_osk.sh looks for osk_sdl in . but Makefile puts it in ./bin

The run_osk.sh script calls make to build the program. The latter puts the binary under bin/osk-sdl. Later on, when the script tries to start the program it looks for the binary in ., however:

export osk_cmd="./osk-sdl -d a -n a -c osk.conf"

I am not sure if run_osk.sh is maybe not meant to be used like this but if it is, I suppose the path should be changed to ./bin/osk-sdl.
