Remove vserver support (fixes #11289)

Browse Source 
This is probably completely unused by now, as vservers have been
superseeded by alternative technology for many years already.

Vservers
--------
If you are using [Linux-Vservers](http://linux-vserver.org/) there are some
special capabilities that different handlers have to make vserver
backups easier.
Set the variable `vservers` to be `yes` in `/etc/backupninja.conf` and see the
example configuration files for each handler to configure the vserver specific
variables.
Additional vserver variables that can be configured in `/etc/backupninja.conf`,
but they probably don't need to be changed:
- `VSERVERINFO` (default: `/usr/sbin/vserver-info`)
- `VSERVER` (default: `/usr/sbin/vserver`)
- `VROOTDIR` (default: `$VSERVERINFO info SYSINFO |grep vserver-Rootdir | awk '{print $2}'`)

## VSERVERS RELATED FUNCTIONS FOR NINJAHELPER
##
## Depends on:
## - easydialog library
## - $conffile
##
## Global variables used and modified here:
## - $vservers_are_available (yes/no)
## - $found_vservers (list)
## - $selected_vservers (list)
## - $host_or_vservers (host/vservers/both)
##
##
## Get vservers-related variables.
## Then, if Vservers are enabled, check that:
## - VROOTDIR is valid;
## - at least one vserver can be found.
## If, and only if, the above conditions are all true:
## - set $vservers_are_available to 'yes';
## - set $found_vservers to the list of all vservers found on the system.
## This function has to be run once before a new helper is run.
## If the argument is "nodialog", use the backupninja's message functions
## instead of easydialog.
