Subject: [PATCH 1/3] avformat/hlsenc: support mkdir_p for use_localtime_mkdir

when use use_localtime_mkdir to create multi level dir,
ffmpeg give error message:
ffmpeg -i ~/Movies/objectC/facebook.mp4 -c copy -use_localtime 1
-use_localtime_mkdir 1 -hls_segment_filename '%Y%m%d/file-%Y%m%d/%s.ts'
out.m3u8
error message:
Could not create directory 20160926/file-20160926 with use_localtime_mkdir
add mkdir_p for support the multi level dir
