Subject[PATCH 1/1] linux/sysinfo.h: Add guarder for struct sysinfo
Date
for all but glibc libc.

This fixes redefinition on MUSL which also defines struct sysinfo when
including <linux/netlink.h> (which includes <linux/sysinfo.h> via
<linux/kernel.h>) and <sys/sysinfo.h>.

glibc loads <linux/sysinfo.h> in <sys/sysinfo.h>.
