rt: signal driver now uses I/O driver directly #5125

  1. rt: signal driver now uses I/O driver directly 

    The signal driver uses a `UnixStream` to receive signal events.
Previously, the signal driver used `PollEvented` internally in order to
receive events on the `UnixStream`. However, using `PollEvented` from
within a runtime driver created a circular link between the runtime and
the `PollEvented` instance.

This patch replaces `PollEvented` usage in favor of accessing the I/O
driver directly. The I/O driver now reserves a token for signal-related
events and tracks signal readiness internally. The signal driver queries
the I/O driver to check for signal-related readiness.
