[SPARK-18658][SQL] Write text records directly to a FileOutputStream
## What changes were proposed in this pull request?
This replaces uses of `TextOutputFormat` with an `OutputStream`, which will
either write directly to the filesystem or indirectly via a compressor (if so
configured). This avoids intermediate buffering.
The inverse of this (reading directly from a stream) is necessary for
streaming large JSON records (when `wholeFile` is enabled) so I wanted to keep
the read and write paths symmetric.
## How was this patch tested?
Existing unit tests.
