Subject: [PATCH] libretro.pcsx2: avoid $NIX_BUILD_TOP

Using $NIX_BUILD_TOP in a Nix expression break under nix-shell (or when
using nativeBuildInputs = [ keepBuildTree ]), so let's avoid it.

Ref. https://github.com/NixOS/nixpkgs/issues/189691

Fixes: fe330c57da8bdd98 ("retroarchFull: fix pcsx2 core installation")
