avformat/hlsenc: use stream's maximum bit rate as fall-back advertised rate

Browse Source 
Enables having proper bit rate values being written into the master
playlist in case of hard-constrained VBR where the maximum bit
rate utilized is known before hand.

Does the same thing as movenc.c, for example.
