[BRLTTY] again cut and paste problem with brltty and at-spi screen drivern

[Halim Sahin]

Hi Samuel,

yes it is ctrl+shift+v and xbrlapi is running as well.

I thought, that brltty is using its own clipboard so that never worked
here.

But I don't need to have the clipboard merged so I thought that brltty
uses it's own clipboard. 
BR.
