py/vstr: vstr_null_terminated_str(): Extend string by at most one byte.
py/vstr: vstr_null_terminated_str(): Extend string by at most one byte.

vstr_null_terminated_str is almost certainly a vstr finalization operation,
so it should add the requested NUL byte, and not try to pre-allocate more.
The previous implementation could actually allocate double of the buffer
size.
