Add plugins dependence package

Add plugins dependence package

The gerrit-trigger plugin is not loaded when install jenkins-plugins because
the lastest version jenkins need to depend on ssh-agent.jpi.

The build-timeout plugin is not loaded when install jenkins-plugins because
the lastest version jenkins need to depend on token-macro.jpi.

The old version jenkins can install these dependence packages,the new does
not.so need to add the files into the jenkins-plugins.
