[HLS] Always set FRAME-RATE attribute 

Although FRAME-RATE is optional per HLS specification, but per HLS
Authoring Specification for Apple Devices (https://apple.co/30n90DC):
  Each EXT-X-STREAM-INF tag MUST have a FRAME-RATE attribute.

Also, iOS and TVos refuse to play the content if VIDEO-RANGE is
present but FRAME-RATE is missing.

Issue #632, #634.
