hotfix 3.11.4: use replacement for postgis-scripts

The previously used Debian package doesn't exit anymore,
so use the package that replaces it, to resolve the
following error during build of the "worker" image:

    Package postgresql-10-postgis-scripts is not available, but is referred to by another package.
    This may mean that the package is missing, has been obsoleted, or
    is only available from another source
    However the following packages replace it:
      postgresql-10-postgis-2.4-scriptsE: Package postgresql-10-postgis-scripts has no installation candidate
