RFR: JDK-8160350 cannot truss jdk9 [solaris]

[Alan Burlison]

Summary:

Microstate accounting has been always-on on Solaris since Solaris 9, the 
use of /proc/self/ctl to enable it is redundant and has the side-effect 
of breaking the use of truss on JVM processes. Microstate accounting 
code removed and other now-redundant *vtime* methods also removed.

Tested with JPRT hostpot testset, all tests passed
