[PATCH] configure: only install bash completion if supported

[Mark Walters]

This LGTM (untested)

I think this is the right way to do this: I don't think we should
spam a user with error messages for attempting tab completion with
an older version of bash-completion (which I think you said was the case
with the other version)

Best wishes

Mark
