Removes the special -I flag specified in the avcodec/bsf/ subdirectory. This makes code copy-pastable to other parts of the ffmpeg codebase, as well as simplifying the build script. It also reduces ambiguity, since there are many instances of same-named header files existing in both libavformat/ and libavcodec/ subdirectories.
