Subject: [PATCH] octavePackages.video: Fix build & install

video uses a slightly different build system from other packages. It
uses an autotools bootstrap script to generate a configure script that
detects the ffmpeg necessities.

HOWEVER, we notably do not actually run the Makefile that the
configure script generates! This pre-build step only creates a
"release tarball"! Octave compiles this "release tarball" in
buildOctavePackage's normal buildPhase with
"octave-cli --eval 'pkg build ...'".
