Revert "Merge commit '8b830ee9a26d47b138f12a82085cdb372f407f1e'" (avconv: Do not try to configure filter outputs without streams)

FFmpeg already tests for this case in configure_output_filter() and printed a
clearer error message

example:
./ffmpeg -f lavfi -i color -f lavfi -i color -filter_complex "[1]null[x],[0][1]overlay" -f null -
before the merge / after the revert:
Filter null has a unconnected output

after the merge / before the revert:
Output pad "default" with type video of the filter instance "Parsed_null_0" of null not connected to any destination
Error configuring complex filters.
Invalid argument

This reverts commit 3e3779cd517e4d2d1f21d5eb6afdb428cd3c1aa0, reversing
changes made to 0b28039a44b33753d77116691d680bd60f3bac1f.
