pform_makewire(): Allow to specify attributes 

There are a few places where pform_makewire() is used and attributes can be
attached to the created net or variable. At the moment pform_makewire()
doesn't allow to specify the attributes, and they either get dropped
silently or with a warning.

Add support for passing the attributes to pform_makewire() which will then
pass it on to pform_set_data_type() to attach it to the declared net or
variable.
