dhcpv4: Avoid a panic in ToBytes() with long strings
When BootFileName is longer than 128 bytes or ServerHostName is longer
than 64 bytes, trying to null-terminate the strings when writing out the
packet causes a panic.
Since the ToBytes() function cannot return errors, silently truncate the
string instead (we do the same with ClientHWAddr if it is longer than 16
bytes for example)
