Sadly we need at least two different forks of flashrom, with
different patches (and therefore different capabilities) applied to
each. This commit parameterizes the flashrom expression and
includes those parameters in the `passthru` so downstream
expressions can check whether various needed features are present.
I accidentally checked in "ectool-patches-of-unclear-provenance.patch",
which was never used in any way by the build expressions.
This file contained my local patches to a very old version of
ectool, some of which came from Debian and some of which I wrote
myself. The `ectool.nix` expression uses a newer version of ectool,
which has upstreamed the relevant changes from Debian. So those
patches no longer need to be carried. The other patches delete
functionality which I don't need, but other people might, so those
patches won't be included in ownerboot.
