py/objmodule: Avoid interning a string unnecessarily.
If the lookup of the module name less the leading "u" is going to succeed,
it's already a qstr (because that qstr is the key in
`mp_builtin_extensible_module_map`). So, use a function that will avoid
interning it if it's not already.
For example, if you `import unavailable` it used to intern the string
`navailable`, but now it won't.
