scrdump: Can specify filename to shutter(1) now, so set it up properly

I went ballistic in commit fb9ab97 ("scrdump: Use shutter(1) instead of
import(1) from ImageMagick", 2012-12-11 14:02:12 +0100) because it
wasn't possible to specify a filename where the screendump should be
stored instead of having to write the filename manually. Things are
better now.

scrdump: Redirect shutter warnings to /dev/null

They're not very interesting:

          (Maybe you should just omit the defined()?)
