rust: update install instruction

As discussed last Friday after publishing the rc wheel, we need to update the
rust readme and highlight that change in the release announcement if we want
people using Rust to keep being able to use pip.

 Users of `pip` can install the Rust extensions with the following command::
 
-  $ pip install mercurial --global-option --rust --no-use-pep517
+  $ pip install mercurial \
+        --global-option \
+        --rust \
+        --no-use-pep517 \
+        --no-binary mercurial
 
 `--no-use-pep517` is here to tell `pip` to preserve backwards compatibility with
 the legacy `setup.py` system. Mercurial has not yet migrated its complex setup
 to the new system, so we still need this to add compiled extensions.
 
-This might take a couple of minutes because you're compiling everything.

 See the "Checking for Rust" section to see if the install succeeded.
