Revert "awful.rules.execute: use delayed_call for emitting request::activate"

The 'request::activate' signal should be sent and handled immediately,
and not delayed.  It was too much of a hack to work around the client
not being visible.

Instead, the "is visible" constraint on `capi.client.focus` will be
removed.

This reverts commit 6963ede3dc.
