misc: Remove sstk from the autogenerated system call list
This change should not have an effect because the system call was
never defined. Also add the misssing attribute_compat_text_section
attribute to the sstk function (a minor optimization). Also update the
NEWS file to document the change.
Fixes commit 9cc93ba0973ad04ee26c515a1552afb85e73c6ba
("misc: Turn sstk into a compat symbol").
