SCTP support of network namespaces appeared in 3.7 kernel =>
all we need is to enable it inside Containers.

Note 1: sctp module is NOT included into the autoload modules list
=> hoster needs to preload the "sctp" module on the host before
CT owners are able to use it. This is done on purpose and not going
to be changed in a while. Reason: too many security issues found in sctp
protocol implementation last year.

Note 2: CRIU does not support SCTP => online migration is known to fail
in case SCTP sockets are used.
