unshare: add more hints about mount namespaces to the man page

There is also idea (by Lennart) to add --propagation=[shared|private|slave|off]
to unshare(1), but it seems unnecessary and too complex as everyone can call
mount(8) after unshare(1) to setup a proper namespace.

libfdisk: (sgi) generate partname according to partition position

The SGI drive currently counts only usable partitions, that's wrong as
Linux kernel counts all partition to generate partition number. For
example:

Kernel:
	sdb                                             8:16   0   600M  0 disk
	├─sdb9                                          8:25   0     2M  0 part
	└─sdb11                                         8:27   0 596.2M  0 part

Fdisk:
	Pt# Device    Info Start       End   Sectors Id System
	 9: /dev/sdb1          0      4095      4096  0 SGI volhdr
	11: /dev/sdb2          0   1220939   1220940  6 SGI volume

setpriv: simplify usage()

Let's keep usage() simple and details in the man page. The current
brief description in usage() seems confusing for some users.

mount: make NAME=value tags usable for non-root

The libmount does not care if we set source or target, it's able to
swap it, but the mount.c function sanitize_paths() does not work as
expected if we set NAME=value as target. It means that

 $ mount LABEL=foo

does not work for non-root users (since 51e3530cdcb1d4f3ab91ae953ebc5adcdc5f9239, v2.24).

This patch also checks if source or target is specified more
than once.

umount: fix umount by tag for non-roots

 $ umount LABEL=foo

currently does not work for non-root users as umount uses the
