test: skip the test-suite runner based on SKIP_LIBINPUT_TEST_SUITE_RUNNER

The current /dev/input/* check isn't reliable enough. So rather than adding
extra heuristics prone to fail add an environment variable that says "do not
run the test suite runner". All other tests are run since they do not
require/modify any specific system setup.
