gdbus: Properly fix encoding of double arrays

Browse Source 
It turns out that this bug actually would (sometimes) impact any sort of
fixed-sized array with an alignment requirement of 8 due to incorrectly
counting the alignment inserted between the (aligned 4) array length and
the actual data.

Fix this properly and remove the exception for doubles.
