remove usage of hardcoded stdlib list when julia_version == VERSION

I'm finding the logic a bit hard to understand here. I'm not sure this does what you want because of the right hand side of the OR

I only want to do the is_unregistered_stdlib check (which looks up stdlibs from a hardcoded list) when julia_version has been explicitly passed in. That way, inconsistencies in that list only affects users who set custom julia_versions. It is similar to the VERSION check in

Pkg.jl/src/Types.jl

Lines 428 to 430 in 610c768

	if !use_historical_for_current_version && julia_version == VERSION
	return stdlibs()
	end

.

Ok. Makes sense

I actually think I originally had it working this way; it must have changed due to some refactoring at some point.
