fast-import: use xsnprintf for formatting headers

The stream_blob() function checks the return value of snprintf and dies. This is more simply done with xsnprintf (and matches the similar call in store_object). The message the user would get is less specific, but since the point is that this _shouldn't_ ever happen, that's OK.
