    info-overview: add build option to control distributor logo
    
    Currently, we display a 256x256 version of the OS icon from
    /etc/os-release. This is too big for my taste, and it's also not
    sufficient for distros that want to display a logo that is not an icon.
    For instance, because we no longer display the operating system name
    immediately beneath the logo, it may be desirable to use a logo variant
    that includes text. This patch adds a meson build option that
    distributions can use to override the logo.
    
    Because the logo might include text, distributions may want to vary the
    logo used in dark mode. A subsequent commit will add a second option for
    this.
