New review comment by dominikschulz on void-packages repository

Comment:
Generating the completion files during package build time cause trouble for some platforms so we decided to generate them when cutting a release and include them in the source package, see https://github.com/gopasspw/gopass/commit/2fdeb0fd42801026afe178a75ce68d0df29de9f7

But I didn't notice the slightly different naming of these files. Should be fixed now.
