Set source of VideoModel to fullname of video file

Some operator will only send the MT the part I (smil) multipart body of Mms
m-retrieve-conf without part II (the real mutimedia files) if "src", "Content-
Type", "Name", "Content-Id" and "Content-Location" of the Mms m-send-req are
set to the full path in MT.

So MT will retrieve a Mms recognized as a Video Mms, but with no parts in
this case.
