Fix 01-translate.t.
Fix old problem in testing module.

There was a dist name as a prereq in the testing module.
Prereqs should only be module names. This was being
ignored but because of better error checking was now
causing an error.
Fix bug in _get_pkgvars. Empty arefs were present.

If conflicts, makedepends, or checkdepends are empty they aren't present
in the result of _get_pkgvars.
Empty depends and makedepends are present in pkgvars, for backwards compatibility.

This might otherwise screw up custom templates out there. This
should also fix the confusion of t/05-custom_template.t.
Fix t/05-custom_template.t. The depshash key was renamed to pkglinks.
Update get_pkgvars POD.
Update Changes for upcoming release 1.27.
Increment module version to 1.27.
Remove boilerplate pod tests because they dont help much anyway.
