`ui5 build` command mistakenly minifies support rules

[codeworrior]

Expected Behavior

After a full build, the support rule files (*.support.js) still should not be uglified to keep them readable in the editor of the UI5 Support Assistant.

Current Behavior

The ui5 build command also uglifies *.support.js files and creates *.support-dbg.js files for them. This differs from the official downloads.

Steps to reproduce the issue

1. Build one of the OpenUI5 libraries with ui5 build and check the content of the output directory
