Add preliminary IceCat-specific privacy settings for 78.

* data/patches/icecat-preferences.patch: Port the patch originally
created for the 68 series, and that was recently removed in
1fffb85edab4533b87b34dd24c5144d6748cb594 due to being incompatible, to
the 78 series.  We would likely do more with this, per
https://lists.gnu.org/archive/html/gnuzilla-dev/2020-09/msg00008.html,
but this is a good enough starting point and nice to have again.
