Paul Chaignon a259c73ddd bpftool: Enable line buffering for stdout 
[ Upstream commit 1a1a0b0364ad291bd8e509da104ac8b5b1afec5d ]

The output of bpftool prog tracelog is currently buffered, which is
inconvenient when piping the output into other commands. A simple
tracelog | grep will typically not display anything. This patch fixes it
by enabling line buffering on stdout for the whole bpftool binary.

Fixes: 30da46b5dc ("tools: bpftool: add a command to dump the trace pipe")
