fork: bump to -rb1 version suffix

Per local/AGENTS.md \xC2\xA7 "Category 2 - Local forks of upstream packages",
all Cat 2 forks must use the `<upstream-tag>-rb<N>` version convention. The
`-rb1` suffix is a Cargo pre-release identifier that prevents upstream
`<upstream-tag>` from silently substituting for this fork in transitive
dependency resolution.

- The base tag (e.g. 0.9.0 for redox_syscall) tracks upstream
  unchanged.
- The `rb1` part records that one Red Bear patch round has been
  applied on top of the upstream tag.

This is the initial policy enforcement pass. The branch is
considered unfrozen at this point; once a freeze is declared, future
`-rbN` increments will land on a frozen `0.X.Y` branch per
local/AGENTS.md.
