[ndctl PATCH] cxl/test: skip, don't fail, when kernel tracing is not enabled

[alison.schofield@intel.com]

From: Alison Schofield <alison.schofield@intel.com>

cxl-events.sh and cxl-poison.sh require a kernel with CONFIG_TRACING
enabled and currently report a FAIL when /sys/kernel/tracing is
missing. Update these tests to report a SKIP along with a message
stating the requirement. This allows the tests to run cleanly on
systems without TRACING enabled and gives users the info needed to
enable TRACING for testing.

Noticed this behavior in Itaru's test results:
