commands: pass include and exclude options to hg.clone()

commands: pass include and exclude options to hg.clone()

These arguments are defined by the narrow extension. Let's teach
core to recognize them so we can delete some code from the narrow
extension and start to exercise the in-core code for performing a
narrow clone.

We have no way of easily testing it, but this change should result in
.hg/requires having the narrow requirement from the time the file
is written rather than added as part of pull. We'll confirm this when
we delete some monkeypatched functions from the narrow extension in
later commits.

Test output changed because hg.clone() is now receiving patterns
and validation of those values is occurring sooner, before the exchange
code runs and prints the message that was deleted.
