Currently, building vala bindings from a tarball is broken because
spice-client-glib-2.0.deps is missing from the tarball. This commit
adds it to EXTRA_DIST and also makes sure the vala bindings don't
get built/installed unless --enable-vala has been passed to configure.
This means vala must be installed to build the vala bindings from a
tarball. Fixes fdo bug #44000.
Disable usbredir, since it wants to install file in /.
Disable vala for distcheck for 2 reasons: not needed after dist and
binding build issue.
Ship with spice-gtk-3.0 vala bindings

With the (upcoming) introduction of the usb device node acl helper, which
uses policykit, spice_usbredir_channel_connect() may take a long time as
it will be waiting for the helper, which will be waiting for policykit which
may be interacting with the user. So spice_usbredir_channel_connect() will
need to become async, and since spice_usb_device_manager_connect_device
calls spice_usbredir_channel_connect it thus also needs to become async.
Note that this patch only changes spice_usb_device_manager_connect_device's
API to use the standard GIO async API, it is not actually async after this
patch since spice_usbredir_channel_connect is not yet async.
