Change Ice204e86 identified a problem with bitrate undershoot due to

timestamps. This part of the fix only applies to vpxenc.

fix pipe support on windows

STDIO streams are opened in text mode by default on Windows. This patch
changes the stdin/stdout streams to be in binary mode if they are being
used for I/O from the vpxenc or vpxdec tools.

Fixes issue #216. Thanks to mw AT hesotech.de for the fix.
