Chang-Hsien Tsai 95a21e7829 samples, bpf: fix to change the buffer size for read() 
[ Upstream commit f7c2d64bac ]

If the trace for read is larger than 4096, the return
value sz will be 4096. This results in off-by-one error
on buf:

    static char buf[4096];
    ssize_t sz;

    sz = read(trace_fd, buf, sizeof(buf));
    if (sz > 0) {
        buf[sz] = 0;
        puts(buf);
    }
