(MAINT) Bump tk-jetty9 dep to 1.5.2

This commit bumps Puppet Server's dependency on
trapperkeeper-webserver-jetty9 to 1.5.2. This is being done primarily
in order for Puppet Server to utilize some memory leak fixes related to
JMX beans in a HUP/restart scenario that were added in the latest
release.
