tests: restrict a recent SELinux test to SELinux systems

* tests/cp/no-ctx.sh: Since the test diagnoses whether the
intercepted lgetfilecon() calls are actually called or not,
restrict the test to systems where that occurs.
The test cases are minimal on non SELinux systems and should
be well covered by other tests.
