tgt-vlog95: Generate initializers for package variables 

While a package can not have logic defined in it. It can have
variables with initializers. These initializers currently get
ignored when converting the package to a module in the
vlog95 backend.

Make sure packages are treated the same as modules here and
that the initializers are turned into initial blocks in the
generate vlog95 code.
