7057935: com/sun/nio/sctp tests should be moved out of jdk_nio and into their own target, jdk_sctp

[Chris Hegarty]

Kelly, Alan,

The com/sun/nio/sctp tests are run when running the jdk regression tests 
with the makefile in the jdk/test directory. They are currently part of 
the jdk_nio3 target.

SCTP is a niche area and there is no need to have these tests run with 
the nio tests. Also most of them are on the ProblemList.txt since there 
are many kernel issues ( most of which are resolved in the latest 
Solaris 10 update release, but there sill remains a few that will be 
addressed in S10u11 ). The bottom line is that these tests are not 
suitable to be run in JPRT, and give little value to developers not 
actively developing SCTP.

Best to provide a specific jdk_sctp target that can be used when the 
sctp tests are required to be run.
