Locally modified keyboard layouts overwritten on update without asking the user

[Rene Schickbauer]

Locally modified keyboard layouts are overwritten on package upgrades (in my case from 16.04 to 18.04) without asking if the user wants to keep the local version or install the maintainers version.

This leads to problems and extra work for the system administrator.

The correct solution would be (in my opinion at least) to do the same checks for files in /usr/share/X11/xkb/* as is done for (most) config files in /etc.

E.g. check the file against the currently installed package before upgrading, if it differs, ask the user what to do.
