sysinfo: add Flags to Statfs_t if not already there
If there is no f_flags field in statfs_t then rename one of the
f_spare fields, as happened in Linux kernel version 2.6.36. This
fixes the build on CentOS 5.11. The CentOS kernel will hopefully not
fill in the f_spare field, so the resulting flags will be zero.
