cmd/go/internal/modcmd: eliminate a call to modload.LoadedModules

Browse source 
modload.LoadedModules reveals more information than necessary about
whether modules have been loaded lazily. The 'vendor' subcommand
doesn't actually need that much information: it has all of the
information that it needs from prior calls to LoadPackages and
ModFile.

For #36460
