[Buildroot] [PATCH 1/1] package/util-linux: lsfd needs headers >= 3.19

[Buildroot] [PATCH 1/1] package/util-linux: lsfd needs headers >= 3.19

[Fabrice Fontaine]

lsfd depends on kcmp.h which is only exported since kernel 3.19 and
https://github.com/torvalds/linux/commit/3f4994cfc15f38a3159c6e3a4b3ab2e1481a6b02
resulting in the following build failure since bump to version 2.38 in
commit ee978e853a6a4c9bb5ed661c1ae704e79f155a35:

configure: error: lsfd selected, but required linux/kcmp.h header file not available

Fixes:
