CI: Install librpm-dev for Code Coverage

Code Coverage workflow failed:

    -- Checking for module 'rpm'
    --   Package 'rpm', required by 'virtual:world', not found
    CMake Error at /usr/local/share/cmake-3.31/Modules/FindPkgConfig.cmake:645 (message):
      The following required packages were not found:

       - rpm

The cause was that no package with developmental files for RPM was installed.
