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:

Qt 5.11 was downgraded to 5.9 because of two issues:
- spawns errors like

- Google login doesn't work. It just doesn't start embedded webbrowser
Apart from version update:
- remove some packages from `LD_LIBRARY_PATH`. I haven't found any
references for them. Most of them were copypasted from AUR expression
- found an implicit reference to `pidof`, in my case this caused warnings
about mismatched Glibc version. I've found implicit reference to `sh` too,
with Glibc warning too, but I don't know how to fix this, and looks like it's
only a warning
Since the program to be wrapped is already in a different path than
$out/bin, we don't need the complicated dance that wrapProgram uses to
put the wrapper in the same location as the original program. Just tell
makeWrapper to put the wrapper in the final desired output location
instead.
This package does not work on arbitrary Linux systems, only on platforms
for which upstream has provided prebuilt binaries. Fortunately, we have
a list of the platforms we know how to get binaries for: it's exactly
the ones in the `srcs` set.
