Don't access Port._filesystem directly (use Port.host.filesystem instead).

In some places, port.host.filesystem is used while in others
port._filesystem is used. Since the Port object's copy of
the FileSystem object is set based on its Host object, these
are the same.

The purpose of this CL is to make the codebase more consistent,
and it makes it so that Port._filesystem is just a private shortcut
attribute, and is not depended upon.
