PR11234: Ensure __get_argv doesn't overflow

That function was calling strlcpy as if the return value was the number
of bytes copied, but strlcpy actually returns the length of the input
string.  We now use min() to handle the case when it's bigger than the
buffer length, and drop out of the loop when that happens.
