Zoom wouldn't show the "Participants"
dialog box when used in a plasma environment;
precisely, the dialog box failed to show its content.
The problem doesn't exist in other
environments like Gnome or Xfce.
Experiments have shown that clearing the environment variable
`QML2_IMPORT_PATH` before calling Zoom fixes the issue.
I suspect the reason to be as follows:
While the zoom build recipe is called with
`libsForQt5xx.callPackage`, putting `qttools.dev` in zoom's
`PATH` is the only connection to nixpkgs' Qt ecosystem.
Zoom brings its own Qt libraries.
Hence it seems to be a good idea to shield
zoom from access to nixpkgs' Qt files to avoid
problems from version mismatch or similar troubles.
So the commit at hand expands zoom's wrapper script
to clear the Qt-related enviornemt variables
`QML2_IMPORT_PATH` and `QT_PLUGIN_PATH`.

This is done by specifying pkg-config in the makeFlags, ensuring that
the correct pkg-config is injected.

Prevent ytfzf from installing its own updates.
Add all programs that are possibly used in the script to $PATH.
A 10M increase in closure size seems very acceptable.
