Subject: ksmbd: add out-of-tree module

ksmbd is an upstream linux alternative to Samba which is lighterweight
and more performant, especially on underpowered devices.

Moving it here from the packages feed as it is now an upstream kernel
module. Also easier to update as version updates can be coordinated better

The next LTS kernel (5.15) has this included. A depend on kernel < 5.15
will need to be added later.
