[PATCH 1/1] testsuite: add unsupported in case OS corefile is not found

[Christina Schimpe <christina.schimpe@intel.com>]

Even though the core_find proc will log a warning, it's better to log
"unsupported" and then terminate the test.  This will help to avoid
silently skipped tests, when running the testsuite.  Most of the tests
already do that.  This patch adds the missing ones.
