update arch package

[Martinligabue]

In the comments of https://aur.archlinux.org/packages/ntfs2btrfs-git there are some suggestions to fix some problems with the package. I think at least some are pretty easy to fix and shouldn't take too much time, but they would increase the health of that package.
I'm also tagging the maintainer @nicman23
