[PATCH v2] test: Skip tst.depth.sh

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.

See
https://oss.oracle.com/pipermail/dtrace-devel/2025-November/006916.html

Incidentally, there are similar issues for

* test/unittest/pid/err.D_PROC_CREATEFAIL.many.d
but this test is already marked SKIP, apparently for the same reason.
See commit d9423bd79
("err.D_PROC_CREATEFAIL.many.d causes failures in subsequent tests").
The current patch simply seeks to apply the same SKIP to another test.

* test/demo/user/userfunc.d
but this test is marked XFAIL since it needs a trigger

All three tests should be resolved when the underlying problem is
tackled.
