Subject: [PATCH v2 bpf 04/11] bpftool: fix fcntl.h include

Fix the following (on some libc implementations):

  CC      tracelog.o
In file included from tracelog.c:12:
include/sys/fcntl.h:1:2: warning: #warning redirecting incorrect #include <sys/fcntl.h> to <fcntl.h> [-Wcpp]
    1 | #warning redirecting incorrect #include <sys/fcntl.h> to <fcntl.h>
      |  ^~~~~~~

<sys/fcntl.h> is anyway just a wrapper over <fcntl.h> (backcomp
stuff).

Fixes: 30da46b5dc3a ("tools: bpftool: add a command to dump the trace pipe")
