693c5be320 avformat/flvenc: fix timestamp of key frame index
Firstly, the timestamps generated from framerate are inaccurate for
variable framerate mode.

Secondly, the timestamps always start from zero, while pts/dts can
start from nonzero. FLV demuxer rejects such index with message:
"Found invalid index entries, clearing the index".

8bf618884b tests/fate: Remove intermediate file of flv-add_keyframe_index test
Do this by making this test a transcode test.
Also fix the test requirements and don't add this test to FATE_AFILTER;
instead use a new variable and a new target for flvenc-tests.

863ebe6f83 avformat/flvenc: add add_keyframe_index option
Add keyframe index metadata
Used to facilitate seeking; particularly for HTTP pseudo streaming.
 1. read live streaming or file by sequence
 2. if use add_keyframe_index option, add a mark flag at the position,
    use to insert new context at the last step.
 3. add the keyframes *offset* and *timestamp* into a list
 4. if use add_keyframe_index option, shift the metadata data from
    mark flag offset
 5. insert the keyframes *offset* and *timestamp* from the list by
    sequence
 6. free the list
 7. end.

Add FATE test case;
