libbinder: check null bytes in readString*Inplace

This is entirely defensive, since the only real guarantee we have here
from these APIs is that a buffer of a given length is available.
However, since we write 0's here, presumably to guard against people
assuming these are null-terminated strings, we might as well enforce
that they are actually null terminated.
