Fix erroneous skip of test cases for disabled ciphersuites

Browse Source 
Test cases that force a specific ciphersuites are only executed if
this ciphersuite is enabled. But there are test cases (for RC4) whose
goal is to check that the ciphersuite is not used. These test cases
must run even if (or only if) the ciphersuite is disable, so add an
exception for these test cases.
