Fix usage of Zstd build feature.

We do not actually need a SetupFeatureObjcetsDir here, as this build feature
is used unconditionally if it is available (unlike OpenSSL which is not,
and which needs a feature objects directory.) It appears FeatureObjectsDir
expects to be called unconditionally, i.e. in an "else" as well as "if",
so this actually caused some build oddities.

Additionally, since it is built unconditionally if available, we have
to put it outside the "regular" checks in the PackageInfo so that it
will be included in the images. This fixes booting @minimum images,
which was apparently broken at some point when "zstd" was inadvertently
removed.
