netfilter: nf_tables: flow_offload depends on flow_table 

Without CONFIG_NF_FLOW_TABLE, the new nft_flow_offload module produces
a link error:

net/netfilter/nft_flow_offload.o: In function `nft_flow_offload_iterate_cleanup':
nft_flow_offload.c:(.text+0xb0): undefined reference to `nf_flow_table_iterate'
net/netfilter/nft_flow_offload.o: In function `flow_offload_iterate_cleanup':

nft_flow_offload.c:(.text+0xc64): undefined reference to `flow_offload_add'
nft_flow_offload.c:(.text+0xc94): undefined reference to `flow_offload_free'

This adds a Kconfig dependency for it.

This option adds the "flow_offload" expression that you can use to
