    build: Reuse characters name variable
    
    gnome-characters uses an input file as a template to generate a
    service file that has two tags for `PACKAGE_NAME` and `pkgdatadir`.
    
    The `PACKAGE_NAME` tag should be replace with the project name, so
    meson's build file uses the `project_name` function to access it.
    However, there is already a variable to access faster to this value
    and to maintain it consistently among every use of it.
    
    This has been changed so `PACKAGE_NAME` also uses that variable.
