Unbuffer all tests that rely on stdio
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).
