internal/export/idna: avoid memory leak in validation codes

These functions have same issues.
* validateRegistration
* validateAndMap
* validateFromPunycode
When string does not hold enough bytes,
lookupString will return 0 for the size.
In this case, we should raise runeError.
This is the way that we can avoid infinite loop.

Fixes: golang/go#22184
