Now that we are using absolute paths we can remove some of the sys.path
mangling that appears in the tools.
We only need to add the path to 'tools/' so that everything can find
modules relative to that directory.
The special paths for finding pylibfdt remain.

At present patman sets the python path on startup so that it can access
the libraries it needs. If we convert to use absolute imports this is not
necessary.
Move patman to use absolute imports. This requires changes in tools which
use the patman libraries (which is most of them).

Python does not like the module name being the same as the module
directory. To allow dtoc modules to be used from other tools, rename
it.
