dpdk: Fix dpdk logs being split over multiple lines.

More recent versions of the vprintf() implementation in glibc are exhibiting this truncation behavior due to an internal buffer size change. According to the glibc developers, this is not considered a bug (see: https://sourceware.org/bugzilla/show_bug.cgi?id=31137). To prevent buffer truncation, remove the request for unbuffered output.
