codec-utils: properly determine AAC Level

Table 1.10 – "Levels for the AAC Profile" only goes to 5 max channels / 7 max channel post amendmend, so I assume the number of channels should not include LFE, otherwise there's no valid level for 5.1 resp. 7.1 (post amendmend) Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-plugins-base/-/merge_requests/680>
