[wallet] Use global g_wallet_init_interface to init/destroy the wallet.

This commit creates a global g_wallet_init_interface, which is created
in bitcoind and bitcoin-qt. g_wallet_init_interface is used to init
and destroy the wallet.

This removes the dependency from init.cpp on the wallet library.
