[Buildroot] [PATCH 1/1] keepalived: Allow the package to be selected only if linux-headers >= 3.4

[Ilias Apalodimas <apalos@gmail.com>]

Hello everyone,

This patch fixes build issues of keepalived reported here:
http://autobuild.buildroot.net/results/770d8fd2f3bacbdbe233da1b4d6e64e20a84d5a5
http://autobuild.buildroot.net/results/1adb710b915427f681eae37452a0942833ce533e
http://autobuild.buildroot.net/results/70b31547e51ec7213372d2ef07bec34c5df77560

These builds are all using an external toolchain and linux-3.2 headers.
Keepalived includes linux_ip_set.h when ipset package is enabled,
which conflicts with linux xt_set.h header(prior to 3.4).

As Yann Morin suggested we are making keepalived depending on the kernel-headers
version.

Regards
Ilias
