If qemu-nbd is not present at the host system, only accept raw images
as input media. This is a workaround for ancient systems like CentOS 6.x
where the nbd module is not compiled in the default kernel and the qemu
package does not include the qemu-nbd executable.

Do not use qcow2 to snapshot images that are raw. qemu-nbd is not
present in some old systems like CentOS 6.x. All we can do to support
those systems is to use the device mapper in as many cases as possible.

This complies better with the python conventions

 * Detect if x2goserver is installed
 * Detect the image's desktop environment
 * Update REMOTE_CONNECTION with the valid x2go entries

For now only ssh is detected

Do not search for specific words in it. The messages may be in a
language other than English. Focus on the Numbers.

is a regular file.
