Stopping maintenance of vim on S9

[Laurent Blume]

Hello all,

Just a heads up: at patch level 7.4.622, the vim recipe on S9 does not
work anymore. I've looked at the error, scratched my head, and for two
seconds, even considered connecting to one of the S9 to have a look.
Then common sense prevailed, and I just removed it from the build.

The one still in the repo will have to do for those poor souls that have
been sent to that particular circle of Hell.

Laurent
