Subject: bin/wakey.sh: Don't vomit at the terminal if the active window is dead.

bin/wakey.sh: Don't vomit at the terminal if the active window is dead.

I don't care about the error here: if `xwininfo' fails, then all that
happens is that I miss some (or all) of the window-ids, which is fine by
me.  In particular, if this happens with the terminal window, then I've
got nothing to complain into anyway.
