info-overview: Look for -text and -dark logo variants

Browse source 
When loading the LOGO icon name from /etc/os-release, append -text to
prefer a textual variant of the logo if it exists, and -dark if the
theme variant is dark.

This allows distributors to ship textual and dark variants of their
logos without adding more fields to /etc/os-release, or more code
specific to logo handling for specific distributions.

$LOGO: default icon
$LOGO-dark: default icon when dark theme is used
$LOGO-text: icon with text
$LOGO-text-dark: icon with text when dark theme is used
