package/network-manager: bump to version 1.22.10

package/network-manager: bump to version 1.22.10

Add COPYING.LGPL to license files, disable the "cloud configuration"
tool. It requires libcurl and it is too unlikely to be useful.

The library license is now LGPL-2.1+.

The hash of CONTRIBUTING has changed because it now refers to
LGPL-2.1+ instead of LGPL-2.0+.

The hash of COPYING is changed due to white-space changes, and the
removal of an introduction text:

    Unless a COPYING file in a subdirectory or file-specific license
    headers specify a different license, the following applies to all
    files in this directory and all subdirectories.

 - fix hash of CONTRIBUTING
 - expand commit log
 - drop GFDL license information, since documentation is not installed
   on the target]
