mkinitcpio-nfs-utils: support NFSv4 roots
https://github.com/void-linux/void-packages/pull/41560

Description:
The `net` hook for `mkinitcpio` shipped by this package uses a helper to do v2 or v3 mounts that support locking without the need for a local `lockd` in the initramfs. The helper does not support v4 mounts and v4 does not require a local `lockd`, so we can look for an NFS version requirement in the root spec and directly call `mount -t nfs4` instead of `nfsmount` to support v4 roots.
