[Buildroot] [PATCH v3 04/13] package/dhcp: systemd: support extra options

["Benoît Thébaudeau" <benoit.thebaudeau.dev@gmail.com>]

Add an OPTIONS configuration variable in order to make it possible to
pass custom extra options to dhcpd. This keeps the systemd support
consistent with the SysV init script.
