RFR(S) JDK-8150973 Hotspot agent use of sun.boot.class.path needs to be updated for Jigsaw

[Dmitry Samersoff]

Everybody,

Please review:

http://cr.openjdk.java.net/~dsamersoff/JDK-8150973/webrev.02/

All references to boot class path in SA code is removed.

VirtualMachineImpl.bootClassPath() is the part of
sun.com.jdi.PathSearchingVirtualMachine interface,
cleanup of this interface requires much more efforts,
so I file a separate CR for this work.

src/jdk.hotspot.agent/test/jdi/runsa.sh is part of obsoleted tests,
cleanup of this tests is in progress under a separate CR.


-Dmitry
