nfct: remove lazy binding
Since cd5135377ac4 ("conntrackd: cthelper: Set up userspace helpers when
daemon starts"), userspace conntrack helpers do not depend on a previous
invocation of nfct to set up the userspace helpers.
Move helper definitions to nfct-extensions/helper.c since existing
deployments might still invoke nfct, even if not required anymore.
This patch was motivated by the removal of the lazy binding.
Phil Sutter says:
"For security purposes, distributions might want to pass -Wl,-z,now
linker flags to all builds, thereby disabling lazy binding globally.
In the past, nfct relied upon lazy binding: It uses the helper objects'
parsing functions without but doesn't provide all symbols the objects
use."
