This patch adds ability to libstore to open a device node that is not a
mach device.
This is in preparation for rump kernel to provide disk access.

Tested as follows:

demo@debian:~$ sudo settrans /dev/z0 /hurd/devnode hd2
demo@debian:~$ sudo settrans /dev/hd2 /hurd/storeio /dev/z0
demo@debian:~$ sudo showtrans /dev/hd2
/hurd/storeio /dev/z0
demo@debian:~$ sudo showtrans /dev/z0
/hurd/devnode hd2
demo@debian:~$ sudo fdisk /dev/hd2

Welcome to fdisk (util-linux 2.29.2).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

Command (m for help): p
Disk /dev/hd2: 10 MiB, 10485760 bytes, 20480 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x00000000

Command (m for help):

See attached for patch.
