Fix javadoc for @see reference in MatrixAggregator

Fix SCMTriggerCause javadoc to deprecated constructor

Fix javadoc link in MatrixExecutionStrategy

Uses the outer class plus the inner class to name the argument, which
satisfies javadoc.

http://javadoc.jenkins-ci.org/hudson/matrix/MatrixAggregator.html#startBuild()
has an @see reference which should be a link.

http://javadoc.jenkins-ci.org/hudson/triggers/SCMTrigger.SCMTriggerCause.html
includes a deprecated constructor with an @{link } reference to the
preferred constructor.  That link is broken in the current javadoc.
This fixes the broken link.
