Subject: devlink: fix libc and kernel headers collision
Since commit 2f1242efe9d ("devlink: Add devlink health show command") we
use the sys/sysinfo.h header for the sysinfo(2) system call. But since
iproute2 carries a local version of the kernel struct sysinfo, this
causes a collision with libc that do not rely on kernel defined sysinfo
like musl libc:

struct sysinfo {
^~~~~~~
Move the sys/sysinfo.h userspace header before kernel headers, and
suppress the indirect include of linux/sysinfo.h.
