Matteo Valdina 83886ced66 libs: encoder: h264,h265: extend max periodic keyframe. 
Increased max values of periodic key frame for h26x codecs.
This allow more fine tunning of encoder that in certian scenario
want higher periodic key frame.

For example: it doesn't want a key frame each 10 seconds but
each 120 seconds.
