pkgs: linux-show-player: fixes final issues.

* do not do double wrapping. See: https://github.com/NixOS/nixpkgs/blob/nixos-23.11/doc/languages-frameworks/gnome.section.md#when-using-wrapgappshook-with-special-derivers-you-can-end-up-with-double-wrapped-binaries-ssec-gnome-common-issues-double-wrapped
  there is probably a better of doing this, but for now this works.
* finally fix gi issues, NixOS/nixpkgs#56943 (comment) helped, but including wrapGAppsHook was also part of the fix.
* cleanup dependencies, there is no need for gi to exist in propagatedBuildInputs and BuildInputs.
