targets.genericLinux: include additional directories in XCURSOR_PATH (#2902)

Browse source 
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. [1]
