RFR(XS): 8066589: Make importing sa-jdi.jar optional on its existance

[Dmitry Samersoff]

Volker,

Please notice, there is work-in-progress to cease out any dependencies
to jdk.hotspot.agent from other modules.


Please, see:

https://bugs.openjdk.java.net/browse/JDK-8059038
https://bugs.openjdk.java.net/browse/JDK-8059035
