I'd like review for:
  939 SUNWdtrt needs to be willing to use 64bit java

Tests of the DTrace Java API had an implicit assumption that the
target process would be 32bit (the same as the java interpretter).
Since ksh is run under isaexec, this assumption stopped holding,
breaking a handful of the tests when run on a 64bit system.  This
changes the jdtrace wrapper such that it will attempt to execute
/usr/java/bin/<64bitname>/java, falling back to /usr/java/bin/java on
32bit systems (but, importantly _not_ falling back on 64bit systems),
which seems more robust than attempting to keep all the tests
presenting 32bit targets.   This introduces a dependency on
runtime/java/runtime64 (the dependency on 32bit runtime already
existed logically, but wasn't in the package, so I added that too).
