[Buildroot] [git commit] package/mrouted: ensure multicast routing is enabled in kernel

[Yann E. MORIN]

commit: https://git.buildroot.net/buildroot/commit/?id=5583a23f157997be294e540f115c19f6478181c4
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

IP_MULTICAST depends on CONFIG_NET and CONFIG_INET, but those are really
depp-core symbols, and anyone enabling mrouted will be expected to
already have networking and TCP/IP supports enabled already in their
kernel configuraiton.
