  Ensure that mbstowcs does not overflow its buffer

Similar to one of the changes by Tim Angus in fd986da: mbstowcs' third
argument is the number of wchar_t available in dest, not the number
of bytes.

This does not appear to be exploitable, because ioquake3 does
not actually call mumble_set_identity() or mumble_set_description()
anywhere, but it might be relevant to derivatives.

Spotted via compiler warnings.
