Fix reloading in plugin/pprof. (#3454)

Browse source 
* Fix reloading in plugin/pprof.

Reloading the server without changing the listen address results in an
error because Startup is called for newly set up plugins before Shutdown
is called for the old ones.

* Use pkg/reuseport when listening.

Use coredns' newly added reuseport.
