Yonghong Song d317b0a8ac libbpf: Fix a compilation error with xsk.c for ubuntu 16.04 
When syncing latest libbpf repo to bcc, ubuntu 16.04 (4.4.0 LTS kernel)
failed compilation for xsk.c:
  In file included from /tmp/debuild.0jkauG/bcc/src/cc/libbpf/src/xsk.c:23:0:
  /tmp/debuild.0jkauG/bcc/src/cc/libbpf/src/xsk.c: In function ‘xsk_get_ctx’:
  /tmp/debuild.0jkauG/bcc/src/cc/libbpf/include/linux/list.h:81:9: warning: implicit
  declaration of function ‘container_of’ [-Wimplicit-function-declaration]

  src/cc/CMakeFiles/bpf-static.dir/build.make:209: recipe for target
  'src/cc/CMakeFiles/bpf-static.dir/libbpf/src/xsk.c.o' failed

Commit 2f6324a393 ("libbpf: Support shared umems between queues and devices")
added include file <linux/list.h>, which uses macro "container_of".
xsk.c file also includes <linux/ethtool.h> before <linux/list.h>.

In a more recent distro kernel, <linux/ethtool.h> includes <linux/kernel.h>
which contains the macro definition for "container_of". So compilation is all fine.
But in ubuntu 16.04 kernel, <linux/ethtool.h> does not contain <linux/kernel.h>
which caused the above compilation error.

Let explicitly add <linux/kernel.h> in xsk.c to avoid compilation error
in old distro's.
