[Buildroot] [git commit] dhcp: S80dhcp-server: also source /etc/default/dhcpd.conf for INTERFACES

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=5eb54fc0950825664824aa4ef100036efd3b5be6
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Similar to how we do it for dhcpd.service. The file should really have been
named /etc/default/dhcpd instead, but changing it now would break existing
systemd setups so leave it as it is.
