Use a placeholder ID for devices missing a system ID

Browse Source 
[ Merge of http://go/wvgerrit/139343 ]

The CDM needs to report a system ID to apps on devices where L1
OEMCrypto implementations that are currently waiting for a new
keybox.  A placeholder system ID is now used.  This ID cannot be
used for DRM certificate requests or license requests.

Device ID has a similar issue, but it might not effect all devices.
If getting the device ID fails due to a missing keybox, it will
return an empty device ID.
