[Kaltura] Skip failing Kaltura_1 test

Fails like so:
> /Users/jhawk/src/youtube-dl/youtube_dl/extractor/kaltura.py(266)_real_extract()
-> data_url = info['dataUrl']
(Pdb) info
{u'message': u'Entry id "0_l5ye1133" not found', u'code': u'ENTRY_ID_NOT_FOUND', u'args': {u'ENTRY_ID': u'0_l5ye1133'}, u'objectType': u'KalturaAPIException'}

Also note another URL to the same video, which might be helpful in
figuring out the right Kaltura entry ID, at least maybe?
