cli: main: allow use of multiple package names in solution-based queries 

Query types like --print-requires, --print-requires-private and --print-provides
can be used in practice to query information about a calculated solution rather
than a single package.

Allow this to be done where it makes sense to allow it, while continuing to restrict
package-specific queries (like --variable= and --variables) to single packages.

Fixes: 541de8bd ("main: handle query selectors that are only usable for single packages correctly")

Closes: #366
