netfilter: ip6t_MASQUERADE: add dependency on conntrack module
After commit 4d3a57f23dec ("netfilter: conntrack: do not enable connection
tracking unless needed") conntrack is disabled by default unless some
module explicitly declares dependency in particular network namespace.
Fixes: a357b3f80bc8 ("netfilter: nat: add dependencies on conntrack module")
