cancel running selection requestcancel-running-selection-request

When using X security extensions to run urxvt as trusted X client and
requesting a selection from an untrusted client, then no X event will be
received, but the selection request will timeout instead.  This patch
cancels any running request before creating a new one, so that the user
doesn't have to wait 10 seconds for the timeout before being able to
initiate a new one.
