portage: Add support for --changed-use

The `--changed-use` flag is an improvement over `--newuse` because it
does not trigger rebuilds for USE flag changes that would not affect the
installed package. Its use is generally recommended over `--newuse`.

service: use self.changed in service_enable_rcconf().

This sets the "changed" result of the module when a rc file is modified.
Previously only --check mode would show that it was going to change.
Can override each role's install path

Defaults to the system wide `roles-path` when `path` is not specified in the
provided `role-file`.  An example installing nginx to a relative path specified
by the `role-file`.
