lsmashsource: unstable-2019-09-15 -> 1141.0.0.0

VFR-maniac/L-SMASH-Works has not had any commits since 2019, and
there is an actively-developed fork under HomeOfAviSynthPlusEvolution.
1141.0.0.0 is the latest release that we can use without overriding
ffmpeg in nixpkgs, because later releases only build against
bleeding-edge ffmpeg.
