[Bug] Liveliness token keyexpr is not registered properly

[pdematteis]

Describe the bug

_z_declare_liveliness_token() in net/liveliness.c is supposed to register tokens in the _local_tokens map by using _z_liveliness_register_token().

For this, the following code is used: _z_liveliness_register_token(_Z_RC_IN_VAL(zn), id, keyexpr);
Unfortunately at this point the keyexpr is empty, since it has been stolen by _z_make_decl_token() -> _z_keyexpr_steal().

The following code should work better: _z_liveliness_register_token(_Z_RC_IN_VAL(zn), id, &declaration._body._decl_token._keyexpr);

Do you confirm?
Thanks.
