v0.8.1 creates much larger artifacts than v0.8.0

[itchyny]

I noticed that the latest goxz, version 0.8.1, creates larger artifacts. Especially for zip archives. Here's reproduction using goxz repository.

 % docker run -it --rm -v $PWD/:"/${PWD##*/}" -w "/${PWD##*/}" golang /bin/bash
root@465e75a8b369:/goxz# go install github.com/Songmu/goxz/cmd/goxz@v0.8.0
...
root@465e75a8b369:/goxz# goxz -n goxz -pv=v0.8.0 ./cmd/goxz
...
[goxz] Success!
root@465e75a8b369:/goxz# go install github.com/Songmu/goxz/cmd/goxz@v0.8.1
go: downloading github.com/Songmu/goxz v0.8.1
