[gnome-user-share/wip/hadess/use-systemd-variable] build: Install in /usr/lib instead of /usr/lib64 on Fedora

    build: Install in /usr/lib instead of /usr/lib64 on Fedora
    
    When building gnome-user-share in Fedora, gnome-user-share-webdav.service
    ends up incorrectly placed in /usr/lib64/systemd/user. It should be in
    /usr/lib/systemd/user.
    
    This is caused by us building a path from scratch, so that the prefix
    could be overridden when doing an installation into a staging directory,
    as the path supplied in systemd's pkgconfig file was broken in this
    regard. This was however fixed in:
    https://github.com/systemd/systemd/issues/9595
    so use this instead.
    
    Closes: #22
