LP#1613326 change UNIVERSAL::can import, style

Remove deprecated (and now fatal) attempt to import a function from
UNIVERSAL.

To quote perl5220delta:

> use UNIVERSAL '...' is now a fatal error
>
> Importing functions from UNIVERSAL has been deprecated since
> v5.12, and is now a fatal error.

Also, adjust the style by which we call "can" on $self->{ils}

Thanks to Blake at MOBIUS for originally reporting this issue, and
proposing a fix.
