ruby: remove unnecessary code.

1) Removing files from the ruby build left some unresovled
symbols. Those have been fixed.

2) Most of the dependencies on Simics data types and the simics
interface files have been removed.

3) Almost all mention of opal is gone.

4) Huge chunks of LogTM are now gone.

5) Handling 1-4 left ~hundreds of unresolved references, which were
fixed, yielding a snowball effect (and the massive size of this
delta).
