Adam Joseph 4a701a51aa spice-gtk: fix build for withPolkit==false case
The spice-gtk/default.nix expression provides an option, withPolkit,
to decide whether or not the library should be compiled with support
for polkit.  Currently setting that argument to false results in a
build failure:

  Run-time dependency polkit-gobject-1 found: NO (tried pkgconfig)
  meson.build:207:0: ERROR: Dependency "polkit-gobject-1" not found, tried pkgconfig

It appears that at some point spice-gtk began requiring the meson flag
-Dpolkit=disabled in this case.  This commit adds that flag when
!withPolkit.

# If this package is built with polkit support (withPolkit=true),
# usb redirection reqires spice-client-glib-usb-acl-helper to run setuid root.
# The helper confirms via polkit that the user has an active session,
# then adds a device acl entry for that user.
# Example NixOS config to create a setuid wrapper for the helper:
# security.wrappers.spice-client-glib-usb-acl-helper.source =
# "${pkgs.spice-gtk}/bin/spice-client-glib-usb-acl-helper";
# On non-NixOS installations, make a setuid copy of the helper
# outside the store and adjust PATH to find the setuid version.
# If this package is built without polkit support (withPolkit=false),
# usb redirection requires read-write access to usb devices.
# This can be granted by adding users to a custom group like "usb"
# and using a udev rule to put all usb devices in that group.
# Example NixOS config:
# users.groups.usb = {};
# users.users.dummy.extraGroups = [ "usb" ];
# services.udev.extraRules = ''
# KERNEL=="*", SUBSYSTEMS=="usb", MODE="0664", GROUP="usb"
# '';

spice-gtk is a GTK 3 SPICE widget. It features glib-based
objects for SPICE protocol parsing and a gtk widget for embedding
the SPICE display into other applications such as virt-manager.
Python bindings are available too.
