    build: replace SourceName with PKG_NAME compile unit name
    
    Currently, the same information is stored at the Packages.manifest in
    the 'Package:' variable and also additionally in the 'SourceName:' variable.
    
    So we have for Packages.manifest for strongswan-charon-cmd:
    ```
    Package: strongswan-charon-cmd
    Version: 5.9.11-1
    
    SourceName: strongswan-charon-cmd
    License: GPL-2.0-or-later
    Section: net
    ```
    
    This is not correct. Several installable packages are built from the same
    strongswan source. Therefore it makes more sense that the source name is
    really the source name. In this case the it is 'strongswan'.
    
    After this change the Packages.manifest for strongswan-charon-cmd:
    ```
    Package: strongswan-charon-cmd
    Version: 5.9.11-1
    
    SourceName: strongswan
    License: GPL-2.0-or-later
    Section: net
    ```
    
    In summary. The 'Package' name is the name of the package to be installed
    on the target system. The 'SourceName' is the compile unit from which the
    package was build from. This must be the same for all installable
    packages built from the same compile unit. This commit fixes that.
