Ben Noordhuis 8ae32a9864 bench: fix buffers/buffer-base64-encode benchmark
The test is supposed to measure the performance of the base64 encoder
so move the Buffer#write() calls out of the benchmark section.

The overhead of the calls isn't terrible (about 1-3%) but having
unrelated activity in a micro-benchmark is never a good idea.
