7116189: Export JVM_SetNativeThreadName from Hotspot.

The initial Mac OSX port added a JVM entry point JVM_SetNativeThreadName for
use by the JDK libraries, but failed to export it in libjvm.so on 
Solaris and Linux.
Mike McMahon from the core libs team produced a fix, which is just to add
JVM_SetNativeThreadName to the Solaris and Linux linker mapfiles.
