ruby: write mask method changes w/ manual subsequent initializations

The write mask method was depending on the statically declared block size
to initialize it's internal bitmask.  We change the default behavior to
initialize an empty bitmask (due to the lack of constructors with SLICC's
new); subsequently we immediately initialize the write mask with the size
for objects that need the write mask.
