[PATCH] test: Skip tst.depth.sh

[eugene.loh@oracle.com]

From: Eugene Loh <eugene.loh@oracle.com>

The test asks for very many pid probes.  E.g.,

        pid$target:::entry,
        pid$target:::return,
        pid$target:a.out::,

If it is successful, this can wreak havoc on some systems, in some cases
leading to 1-2 dozen subsequent tests failing due to cascading problems:
poor test clean up, triggers left running, persistent loads, pid=0 not
running, tests timing out, and so on.  These problems require
investigation.

For now, skip the precipitating test.
