This patch forces bin-wrappers regeneration every time a test program
is updated. A bit wasteful, but I don't see a better option (which is
also why I limit this to test programs only).

A similar patch (without "t/helper/") could be applied on
maint/master, otherwise bin-wrappers is still not updated when moving
back from next/pu. And of course the problem will pop up again if you
build old history...
