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.

Changes the default fetcher in the Rust Platform to be the newer
`fetchCargoTarball`, and changes every application using the current default to
instead opt out.
This commit does not change any hashes or cause any rebuilds. Once integrated,
we will start deleting the opt-outs and recomputing hashes.
See #79975 for details.
As explained by Orivej (reformatted from Markdown):
> These (except libsignal-protocol-c) are private dependencies of the
> actual dependencies that should neither be propagated nor added
> manually to dino. For example, libpsl and brotli come from
> libsoup-2.4.pc:
>
> Requires: glib-2.0 >= 2.38, gobject-2.0 >= 2.38, gio-2.0 >= 2.38
> Requires.private: libxml-2.0, sqlite3, libpsl >= 0.20, libbrotlidec, zlib
>
> (To be precise, glib uses utillinuxMinimal rather than utillinux.)
>
> The warnings we see, such as Package 'mount', required by 'gio-2.0',
> not found, come from CMake running both pkg-config --libs and
> pkg-config --static --libs to populate both <XXX>_LIBRARIES and
> <XXX>_STATIC_LIBRARIES[1], but dino has no use for the latter.
> Currently these warnings can not be disabled:

> although it can not be detected if a library is shared-only from the
> .pc file alone, and this is just a warning.)
