config: pass both relative and absolute paths to `include` callback
The `include` callback is responsible for loading configs from
`%include` statements. The callback currently gets passed the absolute
path [1] to the config to read. That is created by joining the dirname
of the file that contains the `%include` statement. For PyOxidizer
support, I'm trying to reduce dependence on paths. This patch helps
with that by passing the relative path found in the `%include`
statement (but with username expansion, etc.) to the `include`
callback. It also turns out that the existing callers can easily adapt
to using the relative path. Coming patches will clean that up and then
we'll remove the absolute path from the callback.
[1] The "absolute path" bit is a bit of a lie -- it's going to be an
absolute path if the path that was passed into `config.parse()` was
absolute.
