This change modifies the reported version number for km-config:
if km-config is installed from a debian package, the package
version will be output as well, e.g.:
`km-config version 14.0.252-beta (package version 14.0.252-1+bionic1)`
Otherwise the output will be identical to before:
`km-config version 14.0.252-beta-local`.
This change also modifies the script that sets the version number so
that builds on Jenkins are now detected in addition to TC.
This fixes#4579.
This change adds the localization files to the debian package. It
also updates the path to the localization files so that the installed
files will be found.
