Devserver: make the shadow file easier to use

Using the shadow config that is installed with the devserver is a pain.
Instead, let's always use it from the source dir.

Otherwise in order to propagate shadow config changes you needed to

cros_workon --host start cros-devutils
sudo emerge -1 cros-devutils

Now after this change it always just works after you save the file.

TEST=Ran it and checked shadow_config path.
