Make the SNMP agent optional when OPENJDK=true and IMPORT_BINARY_PLUGS=false
in order to avoid build breaks if the closed SNMP files are not availaible.

At runtime, the SNMP agent is activated only if -Dcom. xxxxx .management.snmp.port=<port> is
present. The goal of this change is to allow to build a JDK that doesn't contain the
SNMP agent, and throws an UnsupportedOperationException if the 
-Dcom. xxxxx .management.snmp.port=<port> is present.

The jdk/src/share/classes/sun/management/snmp packages depend on
jdk/src/share/classes/com/sun/jmx/snmp 
and jdk/src/closed/share/classes/com/sun/jmx/snmp.

However these packages are only referenced through the sun/management/Agent.java
class which calls sun.management.snmp.AdaptorBootstrap.initialize(). The idea here
is to:

1) use reflection to call sun.management.snmp.AdaptorBootstrap.initialize()
2) skip compilation of sun.management.snmp and com.sun.jmx.snmp when 
   OPENJDK=true and IMPORT_BINARY_PLUGS=false

This should produce a JDK with an rt.jar that doesn't contain the SNMP classes.
