doc/encoders: remove unsubstantiated ffaacenc > fdk-aac claim

After this claim was made in e34e361 kamedo2 did an in-depth ABX
test comparing these encoders:

https://hydrogenaud.io/index.php?topic=111085.0

Result: FFmpeg AAC wasn't as good as libfdk_aac on average.

I know some things have changed since then such as, "use the fast
coder as the default" (fcb681ac) for example, so maybe the situation
is different now.

However, I am unaware of any recent comparison. So without any
substantiation we shouldn't make such a blantant claim.
