p5-Module-Runtime: update to 0.016.

version 0.016; 2017-10-17

  * port t/taint.t to Perl 5.27.5, where re-requiring an already-loaded
    module doesn't trigger tainting

  * skip t/taint.t if the perl empirically doesn't perform taint checks
    but the script got run anyway (which happens with an unsupported
    configuration of the Perl core which some people are using in the
    absence of a supported no-taint configuration)

  * in t/taint.t, use $^X rather than $ENV{PATH} as the primordial
    tainted value to taint a string being tested

  * in documentation, use four-column indentation for all verbatim
    material

  * in META.{yml,json}, point to public bug tracker

  * in META.json, specify type of public repository
