[util] Parse inputs into objects in vendor.py

Before this commit, the vendor code loaded data from hjson files and
then used dictionary lookups (code like desc['upstream']['url']) to
get data.

There are two problems with this. Firstly, the error reporting when a
config file is malformed isn't great: you get to debug a KeyError
generated deep inside the code. Secondly, the code that extracts data
from dictionaries by name is all interleaved with the "business logic"
code.

This patch moves the parsing into the constructor for two classes,
Desc and LockDesc (representing the contents of the config file and a
lock file, respectively). The path resolution logic also gets folded
in to the Desc constructor.

This should cause no functional change
