modules/snipe-it: disable upstream module

NixOS 22.05 will have a module for Snipe-IT, but it's incompatible to
our implementation and the snipe-it package is currently still at 5.x.
So we'll keep our module around and disable the upstream module when
our's is used.  This will give users of our module a chance to migrate
to upstream and upstream a change to update the package to 6.x.
