fix(base): bump redox-scheme 0.11.0->0.11.1 and redox_syscall 0.7.4->0.8.1

Base build was failing with:

  error[E0277]: the trait `From<libredox::error::Error>` is not implemented for `syscall::Error`
  error: could not compile `scheme-utils` (lib) due to 13 previous errors
  error: could not compile `daemon` (lib) due to 6 previous errors

because the workspace pinned redox-scheme 0.11.0 (libredox 0.1.12) and
redox_syscall 0.7.4. The newer libredox 0.1.16/0.1.17 has a different
Error API. Bump both to versions compatible with libredox 0.1.17:

  redox-scheme 0.11.0 -> 0.11.1 (requires libredox 0.1.17)
  redox_syscall 0.7.4 -> 0.8.1 (requires libredox 0.1.17)

This matches the Red Bear base fork at local/sources/base.
