On Linux this comes from the /etc/os-release file. On other systems, it may
come from a variety of sources. You can either use the standard key names
like G_OS_INFO_KEY_NAME or pass any UTF-8 string key name. For example,
/etc/os-release provides a number of other less commonly used values that may
be useful. No key is guaranteed to be provided, so the caller should always
check if the result is NULL.
