Summary:
The `update` hook gets called even for in-memory updates that does not affect
real filesystem (or edenfs). That hook is set to `edenfsctl redirect fixup`,
which adds 0.35s overhead per commit when doing in-memory rebase.
Define a edenfs-only update hook to remove the overhead.
This is part of a stack of optimization that makes a 20s rebase to 5s (0.6s per
commit to 0.07s per commit).

move everything from the top-level directory into an `eden/scm`
subdirectory.
