git+gcf2client: switch to level-triggered wakeups

Instead of using ->requeue to emulate level-triggered wakeups in
userspace, just use level-triggered wakeups in the kernel to
save some user time at the expense of system (kernel) time.  Of
course, the ready list implementation in the kernel via C is
faster than a Perl one on our end.

We must still use requeue if we've got buffered data, however.

Followup-to: 1181a7e6a853 (listener: switch to level-triggered epoll)
