Documentation: add description for net.sctp.intl_enable 

Describe it in networking/ip-sysctl.rst like other SCTP options.
We need to document this especially as when using the feature
of User Message Interleaving, some socket options also needs
to be set.

Fixes: 463118c34a ("sctp: support sysctl to allow users to use stream interleave")

Enable or disable extension of User Message Interleaving functionality
specified in RFC8260. This extension allows the interleaving of user
messages sent on different streams. With this feature enabled, I-DATA
chunk will replace DATA chunk to carry user messages if also supported
by the peer. Note that to use this feature, one needs to set this option
to 1 and also needs to set socket options SCTP_FRAGMENT_INTERLEAVE to 2
and SCTP_INTERLEAVING_SUPPORTED to 1.
- 1: Enable extension.
