Install basename utility into dracut initramfs

vdev_id requires the program `basename` when handling short aliases
defined in `vdev_id.conf` (those defined without a leading path), but
`basename` is not always available in the dracut environment. This
causes the pool device names to change when using `by-vdev/` devices
or (in extreme cases) can make the pool import fail in dracut.

This commit fixes the problem by explicitly installing `basename`.
