cmd/devdraw: handle X11 selections better

Browse Source 
x11-screen.c accepts selection targets with the MIME type
"text/plain;charset-UTF8", but it should do so case insensitively. The
current code draws an error when working with xfce4-terminal 1.0.4,
which sends lower case.  To reproduce, run acme, snarf some text, then
paste in the terminal.  acme will report:
acme: cannot handle selection request for 'text/plain;charset=utf-8' (590)
