Review 8007703: Remove com.sun.servicetag API

[Mandy Chung]

Remove com.sun.servicetag that we no longer support.  This includes
updates the makefiles and so include build-infra to review this
change.

It's solely JDK implementation-specific that was added to
support JDK product registration and service tag as legacy
Sun-software requirement in 2007.
