Update makepkg: install everything instead

I'm working to add [pkgbuild-introspection](https://github.com/falconindy/pkgbuild-introspection) package.  This package allows you to create an .AURINFO file within a `src.tar.gz` package to be ready to upload to the official [AUR](https://wiki.archlinux.org/index.php/AUR_Metadata) repository.
