Subject: [PATCH] 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, and a second build option to
specify a different logo for use in dark mode.
