tests: add script to disable a selected wire protocol capability

This can be used to test that the client and server both fall back to the
previous wire protocol when the capability is not supported.

It is currently used by test-push-http.t and I plan to use it for the HTTP
long argument support tests.

This emulates the effects of an hg pull --rebase in which the remote repo
already has one local mq patch
