arch,base: Stop loading the interpreter in ElfObject.
The interpreter is a separate object file, and while it's convenient to
hide loading it in the code which loads the main object file, it breaks
the conceptual abstraction since you only asked it to load the main
object file.
Also, this makes every object file format reimplement the idea of
loading the interpreter. Admittedly only ELF recognizes and sets up
an interpreter, but other formats conceptually could too.
This does move that limitted hypothetical redundancy out of the object
file formats and moves it into the process objects, but I think
conceptually that's where it belongs. It would also probably be pretty
easy to add a method to the base Process class that would handle
loading an image and also the interpreter image.
This change does not (yet) separate reading symbol tables.
