netfilter: xt_realm: fix unmet direct dependencies

From: Pablo Neira Ayuso <[email-masked]>

scripts/kconfig/conf --silentoldconfig Kconfig
warning: (NETFILTER_XT_MATCH_REALM) selects NET_CLS_ROUTE which has unmet direct dependencies (NET && NET_SCHED)
warning: (NETFILTER_XT_MATCH_REALM) selects NET_CLS_ROUTE which has unmet direct dependencies (NET && NET_SCHED)
