ZIL: Improve write log size accounting
Before this change write log size TXG throttling mechanism was
accounting only user payload bytes.  But the actual ZIL both on
disk and especially in memory include headers of hundred(s) of
bytes.  Not accouting those may allow applications like
bonnie++, in their wisdom writing one byte at a time, to consume
excessive amount of memory and ZIL/SLOG in one TXG.
