On local builds we shouldn't upload errors to Sentry. The
`build-utils.sh` script sets the `UPLOAD_SENTRY` environment variable
for that purpose. Also, Sentry doesn't like having an empty string
as pkgversion (which should no longer happen with the rest of this
change, but...)
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.
