zoom-us: fix launch
Probably due to glibc update, ZoomLauncher became broken when v4l is present in
LD_PRELOAD path. It can be fixed by a) removing ZoomLauncher from startup chain,
so `zoom` is started directly or b) removing v4l from LD_PRELOAD.
The reason v4l was added before was because my video was rotated upside down without it.
Seem like nowadays this is fixed by Zoom itself, so I'm removing it.

This was needed for my webcam to work with zoom-us. v4l2convert is a
wrapper for apps that only support simple bgr24 or yuv420. For these
apps to support webcams that don’t use those formats, we need to use
LD_PRELOAD to get those symbols. Taken from archlinux wiki:
https://wiki.archlinux.org/index.php/Webcam_setup#V4L1_support
otherwise, autopatchelfHook seems to ignore patchelfing the zoom binary
properly, causing it to fail to start:
