Add a timeout multipler for DisplayHelper

Browse source 
DisplayHelper is used to run the event loop until a condition is met
or until a maximum timeout is reached. This timeout varies between
hundreds of milliseconds to a few seconds. When the tests are running
on a machine that is known to be quite under load (Hudson), the
timeouts in the milliseconds are too optimistics as there can be a
lot of other things running at the same time on the machine.

This change adds a multipler (default 1) that can be controlled from
the maven command line, for example:
-Dorg.eclipse.cdt.ui.testplugin.DisplayHelper.TIMEOUT_MULTIPLIER=5
