use net_dropmon.h in sysroot

[chenheyun-github]

Hi， when i use it in yocto. i found something that we can do it best. dropwatch tools compile with local head file,but it not matched with our real head file form kernel.(net_dropmon.h) net_dropmon.h in dropwatch local src/net_dropmon.h. linux kernel also have it in include/uapi/linux/net_dropmon.h

for example,our kernel is linux5.10: diff tmp/work/cortexa57-poky-linux/dropwatch/1.5.4+git-r0/recipe-sysroot/usr/ include/linux/net_dropmon.h tmp/work/cortexa57-poky-linux/dropwatch/1.5.4+git-r0/git/src/net_dropmon.h 1c1,3 < 95a94

  NET_DM_ATTR_REASON,                     /* string */

it will cause missmatch when we use drop watch in lower kernel version(v5.10), will cause dropwatch and kernel drop_monitor module missmatch with netlink talk. we should build it with sysroot which comes from match kernel head file.

please open a pull request for this. You will also need to eliminate the duplicated ennumeration from dropwatch itself
