cmd/go/internal/modfetch: fix conversion of legacy v2 versions

If a legacy requirement file (for example Gopkg.lock) lists
a package x.com/y/z at version v2.0.0, we assume that
is not a module-aware package, so it should be addressed
as a pseudo-version v0.0.0-date-hash.

But the converter was allowing the v2.0.0 through,
which then failed the next time vgo was invoked.

This CL rejects during conversion (meaning they turn
into pseudo-versions) any versions that don't match
the expected major version for the given module path.

Fixes golang/go#24056.
Fixes golang/go#24585.
