[PATCH 2/4] fast-import: use xsnprintf for formatting headers

[Jeff King <peff@peff.net>]

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.
