widl: Fix array alignment bug

[Dan Hipschman]

This patch fixes an array alignment problem.  The align parameter to
type_memsize has to be initialized, to zero in this case, but it is
being set to something else above this call.  The result is that widl
generates code that aligns arrays of chars to 4-byte boundaries.

This doesn't depend on my patches from earlier today, except maybe
for patch offset.
