Make ld-decode into a Python package.

The modules are now all in an "lddecode" package. The scripts that are
useful for end-users will be installed.

I've done this with distutils.core rather than setuptools because it
doesn't need any of the extra stuff setuptools provides, and
distutils.core is usefully less picky about where it installs to.

I've also trimmed some imports that aren't being used.
