vz: check supported controllers

Browse Source 
Because Vz6 supports SCSI(BUSLOGIC), IDE and SATA controllers only and
Vz7 supports SCSI(VIRTIO_SCSI) and IDE only we add list of supported
controllers and scsi models to vzCapabilities structure.
When a new  connection opens, we select proper capabilities values according
to Virtuozzo version and check them in XMLPostParse.
