Support to cert file provided by Fedora

[Richzendy]

Since the first build of libturpial on Fedora, i added a patch to use a cert file provided by Fedora instead the cert file provided by the libturpial sources (is a guideline), in the last versión of libturpial (1.7.0) this is my patch:

             self.ca_certs_file = os.path.realpath(os.path.join(basedir,
                                                   '..', 'certs',
                                                   'cacert.pem'))
+            self.ca_certs_file = '/etc/pki/tls/certs/ca-bundle.crt'

     def __validate_ssl_cert(self, request):
         req = request.split('://')[1]

Must be great if libturpial can do search to a cert file over differents paths and if the cert file provided by libturpial can't be found them search in others paths for example /etc/pki/tls/certs/ca-bundle.crt, if it can be done, them my patch is not necesary anymore.
