bottles: fix GStreamer on 32 bit apps Because of the gst_all_1 input, 64 bit GStreamer was sneaking into the 32 bit libs.

Basically:
```nix
{ buildFHSEnv
, gst_all_1 # Because of this input...
}:
buildFHSEnv {
multiPkgs = pkgs: with pkgs; {
# This is both 32 bit and 64 bit
hello

# ...this is target arch only (bcause the `with pkgs;` doesn't apply in this case)
gst_all_1.gst-plugins-base
};
}
```

This commit removes the `gst_all_1` input to correct that.

Also removes setting `GST_PLUGIN_PATH`, as it doesn't seem necessary anymore.
(That env is the reason why I added the `gst_all_1` input and accidentally causing the issue in the first place. Ugh...)

Closes #207641.
