This forces all tests that rely on stdio to be unbuffered, like
interrupt.exp was adjusted in 6f98576f.
To recap, in some scenarios, GDB or GDBserver can be spawned with
input _not_ connected to a tty, and then tests that rely on stdio fail
with timeouts, because the inferior's stdout and stderr streams end up
fully buffered. Calling gdb_unbuffer_output forces output to be
unbuffered.
See https://sourceware.org/ml/gdb-patches/2015-02/msg00809.html and
https://sourceware.org/ml/gdb-patches/2015-02/msg00819.html.
Tested on x86_64 Fedora 20, native, and against a remote gdbserver
board file that connects to the target with ssh, with and without -t
(create pty).
