httputil: allow full error serving when with devcam

When hacking on e.g. importers, I sometimes want to use devcam with
-hostname, to test with a non local context. In which case, when hitting
an error httputil.ServeError would not print the full error, which
makes it harder to debug.

pkg/blobserver: Modify the definition of the BlobStreamer interface.

Code implementing this interface will use NewBlob(), which has been
modified to return a pointer to blob.Blob. So change the StreamBlobs
function in this interface to also send *.blob.Blob
