tests: added basic check for system trust store

This checks whether the gnutls_certificate_set_x509_system_trust()
and thus the trust list equivalent function operate as expected
and return a positive number of certificates. The test is ignored
in systems where these functions return GNUTLS_E_UNIMPLEMENTED_FEATURE.
