Remove this hard-coded buffer size. In some basic experiments preprocessing

large files, this doesn't seem significantly better than just letting
raw_ostream pick a buffer size.

This code predates raw-ostream's automatic buffer sizing; in fact, it
was introduced as part of the code which would eventually become
raw_ostream.
