Remove e2local and compiled lua libs

Remove e2local and compiled lua libs

Finally get rid of compiled lua libs, an artifact from the past.  Also
remove the confusion around "e2local" which was just e2lib and other
modules bunched together in the past.

Following the removal of e2local, we can also get rid of loading
compiled lua bytecode, except where needed for backwards compatibility.
