zip: rename package to infozip to avoid name collision with tools

Rename "zip" to "infozip" to avoid name collision, as the same
zip package has been introduces to the build tools as zip.
Buildbot does not like that.

Reference to #10985 and #11089 as well as

+	compatible with the popular PKZIP program; however, the command line
+	options are not identical. In other words, the end result is the same,
