CLI: improvements to 'search' and 'install' command output

Previously subcomponents of a virtual component were shown on
search results, and trying to install these would print a bit
vague message: 'Component not found'. As the sub-branches of
virtual component nodes are hidden on GUI, we should also hide
them when using CLI search, and give a more appropriate error
message why the component cannot be explicitly selected for
installation, if the user still tries to do so.

Also some minor refactoring to the handling of supplemental
information about binary type of the running installer/mt.

This change does not fix the possible case of an install script
changing the 'virtual'-state of a component, as it would require
downloading and evaluating the full metadata for repositories (or
components), which would impose a performance penalty to search.
