Fix compilation error for old stable version caused by genlmsg_multicast_allns backport fix pushed middle version. Version 5.15 version 0-169, 6.1 version 0-115, 6.6 version 0-58 have the old genlmsg_multicast_allns version with flags variable. Compiling backport project with these version result in a compilation error. To handle this, introduce a backport function for the affected kernel version.
