Remove some unneccessary storage packages from runtime-install

Anaconda already depends on following packages:
- filesystem tools: btrfs-progs, ntfs-3g, ntfsprogs, jfsutils,
                    f2fs-tools, xfsprogs, dosfstools, e2fsprogs
- libblockdev-lvm-dbus
- udisks2-iscsi

hostname is no longer needed by dracut for iSCSI, see
dracutdevs/dracut@ebe1821
