Nirbheek Chauhan a8ed817d30 avfvideosrc: Use frame duration instead of frame rate
These days you're can use minFrameDuration and maxFrameDuration which
are CMTime with fractional values. That way we don't need to convert
between double and fractions in a really weird way.

This fixes really odd fractional values exposed in caps, like:

2000000/76923, 1000000/37037, 5000000/178571, 10000000/344827, 10000000/333333

Which are actually just 26/1, 27/1, 28/1, 29/1, 30/1

We can also delete a lot of outdated code for iOS versions older than
7.0 by using newer APIs.
