Install spice-html5 from source

'ws://' is currently hardcoded within the spice_auto.html file included
in the packaged release of spice-html5, raising a security error when
accessing consoles over HTTPS.

Remove the existing apt package and install spice-html5 from source
instead since this issue has been corrected as of spice-html5-0.1.6.
