[PATCH nft] include: Remove __init macro definition.

[Varsha Rao <rvarsha016@gmail.com>]

Add nft_init function, which calls _init functions in main.c file.
Remove __init macro definition as libnftables library will be created
soon. Rename realm_table_init() function to avoid ambiguity as
realm_table_rt_init() and realm_table_meta_init() in rt.c and meta.c
files.
