[PATCH iproute2] tests: Dont fail cls-testbed.t if tests/cls dir is empty

[Vadim Kochan <vadim4j@gmail.com>]

Curently tests/cls-testbed.t tries to run any *.t in
tests/cls/ folder but such folder does not exist.

The better solution can be like having a generic mechanism which
allows to SKIP some tests (by return code?).
