This commit appends system-wide icon and pixmap directory and the icon directory in the home-manager profile to the XCURSOR_PATH session variable for the generic linux target. This is necessary because the default prefix for libXcursor resolves to the Nix store which excludes the aforementioned directories from being searched for cursor themes.
